Description: CYCLIC HYDROCARBONS WITH AN AMINOALKYL SIDECHAIN FIELD OF INVENTION This invention enconpasses novel cyclic hydrocarbons substituted with an aminoalkyl s idechain that are useful for inhibiting adverse phys iological symptoms associated with phospholipase A2 and for treating hypoglycemia associated diseases such as diabetes and obes ity . BACKGROUND Phospholipase A2 hydrolyses arachidonic acid containing phospho - lipids , thereby providing substrate to the multiple enzymes of the arachidonic acid cascade . The metabolites of the arachidonic acid cascade are varied and include pros aglandins , thromboxanes , leuko - trienes , or other hydroxylated derivatives of arachidonic acid. The role of phospholipase A2 in the formation of prostaglandins in mammalian metabolism is well known , see W . Vogt , Advances in Prostaglandins and Thromboxane Research , 3 , p . 89 (1978) and P . C . Isakson, et al . , Advances in Prostaglandin and Thromboxane Research , 3 , page 113 , ( 1978) . Generally , these metabolites are beneficial but in certain disease processes or other conditions the excess ive production of arachidonic acid metabolites causes -deleterious consequences such as inflammation , erythema , platelet aggregation, or allergic responses . The inhibition of phospholipase A2 prevents these and similar conditions . The actual inhibition of phospholipase A2 takes place on a cellular level , therefore , administration of phospholipase A2 inhibitory compounds can be by any manner that will allow for phospholipase A2 inhibition in the affected tissues or organs . The precise mechanisms of the disease processes or conditions which s timulate the arachidonic acid cascade are not clearly understood . The essential prerequisite , however , is enhanced activity of the phospholipases which provide arachidonate to the series of reactions designated as the arachidonic acid cascade . One aspect of the present invention is to block the action of the phospholipases and cut off the flow of arachidonic acid into the cascade , irrespective of the stimulus or stimuli which may be present . Thus , the inhibi ¬ tion of phospholipase A2 of this invention is suitable for treating seemingly unrelated diseases whose common element is the s timulation of the arachidonic acid cascade. Hyperglycemia refers to a condition commonly found in patients suffering from mature-onset diabetes mellitus or other diseases which cause impairment of pancreatic function. Hyperglycemic patients with non-insulin dependent diabetes mellitus (NIDDM) with insulin resis¬ tance exhibit elevated serum glucose levels. Failure to adequately control elevated serum glucose levels can cause myocardloischemia, stroke, peripheral vascular disease, lethargy, coma, blindness, kidney failure or death. One important means of treating these patients uses oral antidiabetic agents instead of conventional treatment for hyperglycemic conditions such as restriction of carbohydrate intake or Insulin Injection. INFORMATION DISCLOSURE Some inhibitors of phospholipase A2 are known. Certain local anesthetics have been shown to inhibit phospholipase A2 activity by competing with calcium ion, which appears to be necessary for phospholipase activity, see W. Vogt, Advances in Prostaglandin and Thromboxane Research, 3, p. 89 (1978) and E. Vallee et al., J. Pharm. Pharmacol., 31, pp. 588-92 (1974). R.J. Flower and G.J. Blackwell have shown that certain anti-Inflammatory steroids induce biosyn¬ thesis of a phospholipase A2 inhibitor which prevents prostaglandin generation, see Nature, 278, p. 456 (1979). These steroids are not direct inhibitors of phospholipase A2, but rather stimulate the synthesis of a phospholipase inhibiting factor called lipocortin, lipomodulin, or macrocortin. Some direct phospholipase A2 inhibitors are known. Indomethac- ln„ a drug with anti-inflammatory properties, has been shown to inhibit phospholipase A2 enzymes isolated from the venoms of Rus¬ sell's Viper, Crotalus adamanteus, and bee, and from pig pancreas; see K.L. Kaplan, et al. , Proc. Natl. Acad. Sci. , 75, pp. 2955-2988 (1978) . Bromphenacyl bromide has been shown to inhibit phospholipase A2 by acylating a histidine residue which is at the active site of the enzyme; see K. Roberts, et al., J. of Biol. Chem. , 252, pp. 2405-2411 (1977) . Mepacrine has been shown to inhibit the activity of phospholipase A2 derived from perfused guinea pig lung, see R. Blackwell, et al. , British J. Pharmacy, 62, p. 79-89 (1978). Some butyrophenones are disclosed as phospholipase A2 inhibitors In U.S. Patent 4,239,780. D. P. Wallach and V. J. R. Brown, Bioch. Phar macol., 30, pp. 1315-24 (1981) also refer to several compounds tha inhibit phospholipase A2. U.S. Patent 3,370,070 discloses amino-substituted steroi compounds which are useful as hypocholesterolemic agents, antibac terial, anti-protozoal, and anti-algal agents. The doctoral thesi of L.J. Griggs, "Part I. Synthetic Approaches to 5- and 16-Thiae strone. Part II. Estrone with a Diazacholesterol Side Chain, University of Michigan (1965) discloses amino-substituted steroi compounds with potential hypocholesterolemic activity. U.S. Paten 3,284,475 and P.D. Klimstra, et al., "Hypocholesterolemic Agents. - VI. A- And B-Ring-Modified Azacholesterols" , J. Med. Chem. , 9, pp. 323-26 (1966) also disclose amino-substituted steroid compounds. SUMMARY OF THE INVENTION The present invention is: compounds of formula I wherein R i selected from the group consisting of CH2=CH-CH2-, HO-CH2CH2CH2- , an CH3, wherein R^ is selected from the group consisting of formulas IV- VI, wherein R2 and R3 are methyl or hydrogen, wherein R is hydroge or hydrόxy and pharmacologically acceptable salts thereof; compounds of formula II wherein R is C^^NC^C^O^- or NH 2 CH 2 CH 2 CH2- an pharmacologically acceptable salts thereof; and compounds of formul III wherein the dashed line indicates that the 2-3 bond is saturate or unsaturated and wherein R is hydrogen or methyl. Compounds represented by formula II are useful when it is medically necessary or desirable to inhibit phospholipase A2 in mammalian system. They are particularly useful in treating symptoms or conditions resulting from metabolites produced by the arachidonic acid cascade, hereafter PMC (phospholipase mediated conditions). PMC includes all untoward conditions or symptoms which are the result of the excessive stimulation of the arachidonic acid cascade. These conditions include allergic diseases, inflammatory conditions (including chronic inflammatory conditions such as rheumatoid arthritis), burns, and hypoxic conditions at the cellular level such as coronary infarcts or infarcts of other tissues. In infarct conditions it is desirable to block phospholipase A2 activity to prevent the destruction of the phospholipids which are integral structural components of cellular membranes. Compounds represented by formulas I and III Invention are useful as hypoglycemic agents in treating patients suffering from elevated serum glucose levels resulting from an intpairment of tissue response to insulin and/or an impairment of pancretic Islet function such as non-insulin dependent diabetes mellitus (NIDDM) with insulin resis¬ tance. DETAILED DESCRIPTION The dosage regimen for preventing or treating phospholipase mediated conditions, PMC, by the compounds represented by formula II are selected in accordance with a variety of factors, including the type, age, weight, sex, medical condition of the mammal, severity of the PMC and the particular compound employed. An ordinarily skilled physician or veterinarian will readily determine and prescribe the effective amount of the compound to prevent or arrest the progress of the condition. Typically, the physician or veterinarian employs relatively low dosages at first and then increases the dose until a desired or maximum response is obtained. Because the diseases or conditions caused by the arachidonic acid cascade are varied, methods of administering these compounds to patients must depend on the particular PMC to be treated. Preferred patients to be treated are domesticated animals and humans, the aost preferred patients are humans. Regardless of the route of administration selected, the com¬ pounds used are formulated into pharmaceutically acceptable dosage forms by conventional methods known to the pharmaceutical art. Thus, the compounds can be administered orally in forms such as pills, capsules, solutions or suspensions; rectally or vaginally in forms such as suppositories or bougies; parenterally, either subcutaneous- ly, intravenously, or intramuscularly using sterile injectable forms known to the pharmaceutical art. For treatment of conditions such as erythema the compounds of this invention may also be administered topically in the form of ointments, creams, gels, or the like. Initial dosages of the compounds of this invention are from about 0.003 to 3.0 g per 70 kg mammal per 6-8 hours orally. When other forms of administration are employed, equivalent doses are administered. When dosages beyond 45 mg/kg are employed, care should be taken with each subsequent dose to monitor possible toxic effects. The phospholipase A2 inhibitory compounds of the present invention ameliorates the cellular damage resulting from the degrada¬ tion of cell membranes by phospholipase A2 after hypoxic states suc as coronary infarcts , ligation of the aorta during surgery for aortic aneurys s (resulting in kidney damage), and the like, see Zalewski, et al., Clinical Research 31, p. 227 (1983). Preferred patients to be treated are domesticated animals and humans, the most preferred patients are humans. This is a preferred use of these compounds. The phospholipase A2 inhibitory compounds are useful in the treatment of asthma. Asthma is a lung disease in which a wide variety of stimuli can result in an asthmatic attack. These stimuli could be damp cold air or allergens in the environment. The asthma¬ tic response is initially characterized by constriction of the bronchioles leading to increased airway resistance. This early constrictive phase is due to mast cell release of histamine and other modulators such as peptides. After the constrictive phase, a late sustained phase occurs which, in human beings, may reach a maximum in 6-8 hours. This phase is slower in onset and disappearance and is due to metabolites of the arachidonic acid cascade such as throm- boxanes, prostaglandins, and leukotrienes, see "Corticosteroid Treat¬ ment in Allergic Airway Diseases, "Proceedings of a Symposium in Copenhagen Oct. 1-2, 1981 (Editors: T.H. Clark, N. Myginfd, and 0. Selroos, Munksgaard/Copenhagen 1982). Inhibition of phospholipase A2 at a physiologically acceptable level will prevent formation of these products in the lung thought to be responsible for the "2nd wave" of airway resistance. Preferred patients to be treated are domesticated animals and humans, the most preferred patients are humans. For these uses, the compounds are administered in a variety of dosage forms: orally in the form of tablets, capsules, or liquids; rectally in the form of suppositories; parenterally, subcutaneously, intradermally, or intramuscularly, with intravenous administration being preferred in emergency situations, by inhalation in the form of aerosols or solutions for nebulizers; or by insufflation in the form of powder. These compounds are effectively administered to human asthma patients by oral or aerosol inhalation. Doses in the range of about 0.01 to 50 mg per kg of body weight are used 1 to 4 times a day, the exact dose depending on the age, weight, condition of the patient and frequency and route of admini¬ stration. For the above use these compounds can be combined ad¬ vantageously with other anti-asthmatic agents, such as sympathomi- metics (isoproterenol, phenylephrlne, ephedrine) ; xanthine deriva- tives (theophylline, aminophylline) ; and corticosteroids (pred- nlsolone) . Administration by oral inhalation with conventional nebulizers or by oxygen aerosolization conveniently provides the active ingredi¬ ent in dilute solution, preferably at concentrations of about 1 part of medicament to from about 100 to 200 parts of weight of total solution. Entirely conventional additives may be employed to stabilize these solutions or to provide isotonic media, for example, sodium chloride, sodium citrate, citric acid, sodium bisulfite, and the like can be employed. A self-propelled dosage unit suitable for inhalation therapy for administering the active ingredient in aerosol form comprises the active ingredient suspended in an inert propellant such as a mixture of dichlorodifluoromethane and dichlorotetrafluoroethane together with a co-solvent such as ethanol, flavoring materials and stabiliz- ers. Instead: of a co-solvent, a dispensing agent such as oleyl alcohol can also be used. Suitable means to employ the aerosol inhalation therapy technique • are described fully in U.S. Patent No. 2,868,691. The compounds represented by formula II also control spasm and facilitate breathing in conditions such as bronchial asthma, bronchi¬ tis, bronchiectasis, pneumonia and emphysema. To treat a patient with these symptoms, the compounds would be administered to the patient in the same manner as described above. This is a preferred use of compounds represented by formula II. These novel phospholipase A2 inhibitory compounds are also useful as anti-inflammatory agents in mammals, especially humans, and for this purpose, are administered systemically and preferably orally. For oral administration, a dose range of 0.05 to 50 mg per kg of human body weight is used to give relief from pain associated with inflammatory disorders such as rheumatoid arthritis. They are also administered intravenously in aggravated cases of inflammation, preferably in a dose range 0.01 to 100 g per kg per min until relief from pain is attained. When these novel compounds are administere orally, they are formulated as tablets, capsules, or as liqui preparations, with the usual pharmaceutical carriers, binders, an the like. For intravenous use, sterile isotonic solutions ar preferred. These novel phospholipase A2 inhibitor compounds are usefu whenever it is desired to inhibit platelet aggregation, reduce th adhesive character of platelets, or remove or prevent the formatio of thrombi in mammals. For example, these compounds are useful t prevent myocardial infarcts, to prevent post-operative thrombosis to promote patency of vascular grafts following surgery, or to trea conditions such as atherosclerosis, arteriosclerosis, blood clottin defects due to lipemia, and other clinical conditions. Preferre patients to be treated are domesticated animals and humans, the mos preferred patients are humans. For these uses, these compounds ar administered intravenously, subcutaneously, intramuscularly, or i the form of sterile implants for prolonged action. For rapi response especially in emergency situations, the intravenous route o administration is preferred. Doses in the range about 0.005 to abou 20 mg per kg of body weight per day are used, the exact dose depend¬ ing on the age, weight, condition of the patient, and frequency an route of administration. Phospholipase A2 Inhibitors of the present invention are usefu in the treatment or prevention of conditions due to increase phospholipase activity observed after central nervous system (CNS) trauma such as brain and spinal cord injury, see, E.P. Wei, et al. , J. Neurosurg., 56, pp. 695-698 (1982) and E.D. Hall and J.M. Braugh- ler, Surgical Neurology, 18, pp. 320-327 (1982). Preferred patients to be treated are domesticated animals and humans, the most preferred patients are humans. The compounds represented by formula II are useful to treat PMC symptoms which have already occurred in the mammal or to prevent PMC symptoms in particularly susceptible mammals. Use of these compounds before the development of PMC symptoms prevents the formation of the prostaglandins and similar products causing such conditions. Thus, phospholipase inhibitors of the present invention are used to prevent edema and erythema from sunburn by administering these compounds prior to exposure to sunlight. These compounds are also administered to persons suffering from hayfever or similar allergies prior to exposure to the allergenic substances to which hayfever sufferers are sensitive. It is most preferred to use the compounds of this invention in the treatment or prevention of asthma and in the treatment or prevention of cellular death resulting from hypoxic states. The preferred route in most cases is to systemically administer the compounds in order to allow them to enter the mammal's blood- stream and thus be distributed throughout the mammal's system. In certain cases, where the PMC is of a localized nature (sunburn or psoriasis) , topical administration is employed in order that the phospholipase A2 inhibition is confined to the afflicted area. While conventional treatment for hyperglycemic conditions may include restriction of carbohydrate intake and insulin injection, one important means of treating hyperglycemic patients is with oral hypoglycemic agents. Compounds of this invention represented by formulas I and III are useful to treat NIDDM and its complications In mammals, Including human beings because these compounds lower the serum glucose levels when administered to KKA V mice with spontaneous diabetes. Accord¬ ingly, a patient to be treated with certain of the novel hypoglycemic compounds of this invention is first diagnosed as a diabetic by conventional means, usually by the persistence of elevated serum glucose levels, and a treatment regimen with compounds of this invention is established so that the elevation in a patient's serum glucose level is either significantly reduced or eliminated. The precise therapeutic endpoint of treatment, elimination or merely reduction in hyperglycemla, is readily determined by the attending physician based upon the clinical presentation and concomitantly employed treatment. For example, certain of the novel hypoglycemic compounds of this invention may be employed to significantly reduce hyperglycemia in a patient, with a carbohydrate-restricted diet providing a further measure of control. Preferred patients to be treated are domesticated animals and humans, the most preferred patients are humans. While the novel hypoglycemic compounds of this aspect of the invention may be administered by any convenient route; orally, subcutaneously, intravenously, intramuscularly, topically, or rectally, these compounds are most significantly and usefully employed as oral hypoglycemic agents, particularly in solid dosage form such as capsules and tablets. Alternatively, liquid oral dosage forms, such as syrups and elixirs, are alternatively employed. The solid, oral pharmaceutical compositions in accordance with the present invention are all prepared by methods known in the art for preparing other oral antidiabetic compositions. Since an individual patient response to treatment with compounds in accordance with the present invention may vary, effective dosages of the compounds of the instant invention will vary from patient to patient. Ordinarily, an oral dosage of from 0.1 to 10 mg/kg of these compounds will be adequate to significantly reduce hyperglycemia in a patient being treated. Repeated dosages, every 4-12 hr, may be required during the day to maintain the antihyperglycemic effect. Accordingly, dosages from about 0.1 mg/kg/dose to about 10 mg/kg/dose, depending upon the patient, frequency of treatment, and observed response. An attending physician may at first prescribe a relatively small amount of a novel hypoglycemic compound of this invention and later increase this dosage as necessary to achieve the desired level of control. Novel hypoglycemic compounds of the present invention are also useful to treat and/or prevent obesity in mammals including human beings. For this purpose, the novel compounds of this invention are formulated and administered as described above for hyperglycemia. All compounds of the present invention may be formulated into pharmaceutical compositions, employing a pharmaceutically acceptable carrier. Pharmaceutical formulations include pharmaceutical composi¬ tions suitable for oral, parenteral, vaginal, topical, and rectal use, such as tablets, powder packets, cachets, dragees, suppositor¬ ies, bougies, and the like. Suitable diluents or carriers such as carbohydrates (lactose), proteins, lipids, calcium phosphate, cornstarch, stearic acid, methylcellulose and the like may be used as carriers or for coating purposes. Coconut oil, sesame oil, safflower oil, cottonseed oil, peanut oil may be used for preparing solutions or suspensions. Sweetening, coloring and flavoring agents may be added. In general the preferred route of administration depends on the condition being treated. For asthma, oral or aerosol inhalation is preferred. For most other conditions the preferred mode of ad¬ ministration is oral. The phospholipase A2 inhibitory compounds of this invention are useful in any mammal whose metabolic system includes the phospholip¬ ase induced arachidonic acid cascade. The mammals which are prefer¬ red are generally domesticated animals and humans. Humans are the most preferred mammals to be treated. The utility of the compounds of this invention represented by formula II is demonstrated in the following laboratory tests which determine phospholipase inhibition. Inhibition of Rat Neutrophil Aggregation 1. Method for Thioglycolate Broth Preparation Weigh sufficient thioglycolate medium, USP grade, to prepare a 5% w/v solution in sterile water. Heat the solution for 10 minutes on a boiling water bath. Remove and allow the solution to cool to 20-25 c . Inject 10 ± 0.5 ml intraperitoneally into Sprague-Dawley rats as described below. 2. Method for Rat Peritoneal Leukocyte Collection Six (6) Sprague-Dawley, pathogen free, female rats (230-270 grams) are injected intraperitoneally with 10.0 ± 0.5 ml thioglyco¬ late broth, 5% w/v 16-18 hours prior to sacrifice. After sacrifice by cervical dislocation, leukocytes accumulated in the peritoneal cavity are collected by injecting 30 ml of sterile 0.9% w/v sodium chloride intraperitoneally and vigorously massaging the abdomen to assure uniform dispersion of the cells within the carcass. Use a pasteur pipet to remove approximately 20 ml of fluid with suspended cells from a small incision through the abodominal wall. Collect the cell suspension in plastic culture tubes. 3. Washing and Resuspension of Cells for Aggregation Centrifuge the cell suspensions isolated above for 10 minutes at 1000 rpm (Sorvall RC-3, HG-4L rotor, 25 β C). Discard the super¬ natant. Resuspend the cells evenly in 0.9% NaCl to original volume, centrifuge a second time for 10 minutes at 1000 rpm. Discard the supernatant. Resuspend the cells evenly in Hanks buffer. 4. Determination of Leukocyte Concentration Transfer 10 μl of leukocyte suspension into a plastic cel counting cup. Add 15.0 ml of IS0T0N- diluent for cell counting Determine the cell count with a Model ZBI Coulter Counter or equi valent. 5. Neutrophil Aggregation A. Add 0.5 ml of rat leukocyte (neutrophil) suspension to eac channel of a Payton dual channel aggregometer. Cuvettes, 45 mm x mm i.d., are used. Cell suspensions at 37°C are stirred (400 rpm). B. Add 5 μl test compound (.01 M in absolute ethanol) to cel and evaporate to dryness under nitrogen. Add 0.5 ml cell suspensio (37 C C, 400 rpm). Incubate for 2 minutes, then add 1 μl of th agonist, 10 " M FMLP. C. Record the aggregation trace (% transmitted light) on potentiometric recorder. Inhibition of Hog Pancreas PLA 2 1. Enzymes Both soybean lipoxidase and hog pancreas phospholipase A2 ar obtained commercially from Sigma. The soybean lipoxidase is dis solved at a concentration of 5 mg/ml in 0.033 M ammediol-HCl buffe pH 8.5 with 1 x 10 ' ^M Ca "1-1" . The hog pancreas enzyme is added at th rate of approximately 350 units per ml of final mixture. Thus, 0.02 ml is equivalent to 9 units of phospholipase and 0.125 mg of lipoxi dase. 2. Substrate The substrate is phosphatidyl choline. The material has a fatt acid composition upon saponification, of 2% of 16:0, 1% of 18:0, 3 of 18:1, 18% of 18:2, and 12% of 18:3 fatty acids with the larges fraction being linoleic acid. The estimated molecular weight is 780. 78 mg of this substrate is put in a 10 ml volumetric flas containing 100 mg of deoxycholic acid. A "pill" magnetic stirrer is added along with 7-8 ml of water, and the whole stirred rapidly until all the lecithin is dissolved. The "pill" is then removed and the flask contents are made up to 10 ml with water. 3. Procedure To three oxygraph cells equipped with magnetic stirrers is added 2.5 ml of 0.033 M ammediol-HCl buffer, pH 8.5, containing 1 x 10 " M Ca "1-1" . This is followed by 0.1 ml of the inhibitors made up at an initial concentration of 0.01 M in methanol. Where controls are run, 0.1 ml of methanol is added to each cell. The cells are then put in the oxygraph apparatus and the contents are stirred briefly. 0.025 ml of the enzyme mixture is then added and the electrodes are Inserted in each cell, care being taken to exclude all air bubbles. With the stirrer and water bath pump on, the contents of each cell are stirred for 2.5 minutes at 37.5"C. The reaction is initiated by adding to the cells 0.05 ml of 0.01 M lecithin substrate. The reaction is monitored by continuous measurement of rates of oxygen depletion from the medium as a consequence of unsaturated fatty acids (linoleic acid) being released from esterified form by the phospholi¬ pase. These fatty acids immediately become substrates for the soybean lipoxidase which forms the 15-hydroxy acids, with consequent oxygen utilization. The initial rates of oxygen consumption are recorded using a Sargeant-Welch Recorder set at 5 mV full scale. The "air" setting and medium chart speed are used. The slopes of oxygen consumption are then determined in triplicate, and these are compared with the methanol controls to determine the degree of inhibition. If complete inhibition is seen at the first concentration, appropriate dilutions are made to bring the inhibition percentages down to at least 3 concentrations of inhibitor where partial inhibition is observed. The I50 can then be calculated for that particular inhibitor, using linear regression slopes. All compounds for which I50 value is shown are tested for inhibitory activity on the soybean lipoxidase. None inhibit at the test concentration. The utility of the compounds of this invention represented by formulas I and III is demonstrated in the following laboratory tests which determine sseru glucose levels in mice. Testing For Blood Glucose Lowering In The KKA V Mouse 1. General All KKA V mice used for screening are produced and selected by methods previously outlined, T. Fujita et al., Diabetes, 32, 804-10 (1983) . Groups of 6 animals each are employed. 2. Screening Procedure Pre -treatment nonfasting blood glucose (NFBG) samples are measured 5 days prior to the start of a screening run by previousl described methodologies. These blood sugar values are used to plac animals into groups with equal mean blood glucose concentrations an to eliminate any mice with a NFBG value <250 mg/dl. On day 0 compounds chosen to be run are incorporated into ground mouse cho (Purina 5015) . Compounds are included at a rate of 1 mg/gram o chow. Generally, 300 g of drugs containing diet is prepared for eac group. Mice receiving ground chow only are the negative control Each screening run also uses ciglitazone (T. Fujita, et al., supra as a positive control (0.5 to 1.0 mg/gram chow). Initial body and food weights are taken on day 1. Food i placed in a crock which contains an adequate amount to last for th length of the study. In order to acclimate the mice from pellete mouse chow to ground mouse chow, they are fed the ground chow for days prior to use in the screen. On day 4 of treatment, a NFB sample is again measured, as well as food and body weights. Foo consumption measurements are used to determine an average mg/kg dos the mice received over the ^ testing period, and to evaluate th compound's effect on food consumption. 3. Acceptance of a Screening Run and Determination of Activity Acceptance and activity are determined by the following criter¬ ia: A. Negative Control This group must not show a significant change (p<.05) fro pre-to post-treatment. If there is a significant decrease in blood sugar the run is not valid. B. Positive Control This group must show a significant depression in blood sugar mean levels from pre- to post-treatment. A lack of activity in this group would also invalidate the run. C. Negative Control vs. Positive Control This contrast must be significant. It is a further assurance that both control groups performed as expected. D. Compound A compound's activity is based on several criteria: (1) A significant decrease in blood sugar mean levels from pre- to post- reatment. (2) Negative control vs. compound: This contrast allows one to determine if these groups are dissimilar, which is required for the compound to be considered active.
