Authors: Bach‐Lijour B. , Crochet D. , Grossetete 2 R. , Raffin T. , Nguyen J. M. , Hurtrel M. , Daculsi G. , Nihouannen J. C. LE 
Published: June 2007

SummaryThe long stabilizers of the VT‐LGM filter rest on large areas of the vascular wall. The morphometric study of the layers of the vascular wall, after implantation of filter in 15 ewes, divided into 3 groups of follow‐up (2, 4 or 8 weeks) of 5 animals, was made at 3 levels opposite the filter and 1 level outside of it. Changes are seen for all the layers. Filter produces intimal hyperplasia. Stabilizers are quickly isolated from the blood flow. The thickness of the intimal hyperplasia grows for 4 weeks. It is more important at the base of the filter than at its head. There is also hyperplasia of the media with no change according to the follow‐up or the level opposite the filter. The adventitia becomes thinner without variation of time or level of the filter. Smooth muscle cells of the adventitia become less frequent and smaller. Their density, in front of the stabilizers, is the smallest by 4 week follow‐up and remains the same along the stabilizer. The full thickness of the wall is bigger opposite the stabilizers than between them. The filter produces changes that are limited in time and in space. The most important changes are seen at 4 weeks after insertion and opposite the stabilizers.
The Morphology of the Ureter in the Duck (Anas platyrhynchos)
Authors: Mirabella N. , Esposito V. , Corona M. , Pelagalli G. V. 
Published: June 2007

SummaryThe morphology of the ureter of the duck was investigated, using histological, SEM and TEM techniques. The inner perimeter, the total thickness of the ureteral wall and the thickness of each uretral layer were measured. The epithelium was tall columnar and pseudostratified along all the tracts of the ureter and showed a high muco‐secretive activity. The lamina propria contained numerous capillaries and aggregates of leucocytes and macrophages. Throughout the lamina propria there was a dense plexus of nerves. Some denuded single nerve fibres were observed between the epithelial basal cells. A plexus of nerves was also observed in the tunica muscularis. The ostium cloacale ureteris opened on a well‐developed papilla in the dorsal region of the urodeum. The total thickness of the ureteral wall, the thickness of the lamina propria and the tunica muscularis, and the inner perimeter progressively increased towards the ostium. The above observations suggest that the avian ureter plays an important role in the modification of the urine coming from medullary cones, and in emission of the urine into the cloaca.
Morphologic Peculiarities of the Renal Cortical Vasculature Connected with Blood Redistribution in the Kidney of the Domestic Pig
Authors: Vodenicharov A. , Simoens P. 
Published: June 2007

SummaryThe cortical blood vessels from 2 to 8 month old Camborow hybrid pigs and Belgium landrace pigs were studied using histologic and semithin sections as well as corrosion casts and cleared preparations of intravascular injection.It was established that the cortical blood vessels of the porcine kidney possess peculiarities that may regulate the redistribution of blood in the cortex. These peculiarities were found in the interlobular arteries, in the efferent arterioles of midcortical nephrons, in afferent arterioles of juxtamedullar glomeruli, and in the glomerular capillary networks.It was established that the number of renal corpuscles is different in the various zones of the cortex.

Authors: Vázquez J. M. , Arencibia A. , Gil F. , Ramírez J. A. , González N. , Sosa C. D. , Jaber J. R. 
Published: June 2007

SummaryThe purpose of this study was to define the normal anatomic structures in the canine larynx with magnetic resonance images. TI‐weighted images were taken in the sagittal and transverse planes. The MR images were obtained comparing MR images to dissection planes. Magnetic resonance imaging provides excellent anatomic detail of laryngeal structures. Therefore, it is of value for diagnostic imaging of some respiratory diseases in the dog.
Macro‐Anatomical Investigations on the Skeletons of Porcupine (Hystrix cristata). Part III: Skeleton axiale
Authors: Yilmaz S. 
Published: June 2007

SummaryThe aim of this study was to investigate the axial skeleton of two porcupines (Hystrix cristata).The important features of the skull, observed in this study are as follows: The zygomatic process of frontal bone (os fron‐tale) was found to be rudimentary, and the infraorbital foramen (for. infraorbitale) was very large. The zygomatic bone (os zygomaticum) has two processes (frontal and temporal) and the zygomatic arch (arcus zygomaticum) was composed of three bones.The dental formulae were 2 (I 1/1, C 0/0, P 1/1, M 3/3) = 20. The angular process (Proc. angularis) of mandible is well developed.The vertebral formula was found as C7, T15, L4, S4, Ca12. All of cervical vertebrae had the transverse foramen (for. transversarium).The first eleven spinous processes (proc. spinosus) of thoracic vertebrae were caudally‐sloped, the twelfth as the anticlin vertebrae and the last three were directed cranially.Hemal arches (or ossa arcus hemalis) were presented as separate bones which articulate with the ventral surfaces of the caudal ends of the bodies of the second, third and fourth caudal vertebrae.
Anatomo‐radiographic Study on the Osteogenesis of Carpal and Tarsal Bones in Horse Fetus
Authors: Soana S. , Gnudi G. , Bertoni G. , Botti P. 
Published: June 2007

SummaryThe aim of this study is to point out the time of appearance of the carpal and tarsal bones in the fetal horse, considering an estimated fetal age, to follow their morphological development through to birth, and to characterize possible abnormal shape and/or delay of their ossification. The right carpal and tarsal region of 140 equine fetuses of both sexes (71 males, 69 females) and different ages (from 70 to 340 days of gestation) were examined radiographically in order to identify the sites of ossification from their earliest appearance. The times of appearance of the sites of ossification of the carpal bones are chronologically stated for each bone.
An Avian Model for Comparative Studies of Insulin Teratogenicity
Authors: Julian D. , Abbott U. K. 
Published: June 2007

SummaryThis study was designed to explore the effects of purified insulin during early stages of chick embryo development, and to search for variations between different molecular structures of the hormone. Chicken embryos were treated in ovo with a single dose of insulin (porcine or bovine), in only one stage of development between day 0 and day 9. Two susceptible periods were found. The earliest period (day 0 to day 3), characterized by abnormalities in the caudal vertebrae and a high mortality rate, was followed by a period with a different set of malformations, a syndrome classified as achondroplasia. The rate of achondro‐plastic embryos was significantly higher with porcine rather than with bovine insulin. Paradoxically, insulin at physiological doses has stimulatory effects in growth and development but, in contrast, has inhibitory effects at higher doses. The precise signalling cascade of events in the target cells is still unclear. The possible interpretations of our results are discussed. The similarity between the insulin‐induced abnormalities in the chicken embryos and the caudal regression syndrome, the most common malformation found in infants of diabetic women, suggests a common mechanism. This circumstance offers the chicken embryos as an excellent in vivo model for research on the mechanism of action of insulin during normal and abnormal development.
Tongue Papillae in Goat: a Scanning Electron‐Microscopic Study
Authors: Kumar P. , Kumar S. , Singh Y. 
Published: June 2007

SummaryThe tongue papillae of 6‐9‐month‐old Jamunapari goats were studied by scanning electron‐microscopy. The conical‐shaped filiform papillae had 3–6 pointed projections and 6–8 secondary papillae at the free tip and the base of the dorsal surface of the tongue, respectively. The convex surfaced fungiform papillae were raised above the lingual mucosa. The vallate papilla was characterized by a papillary groove and an annular pad. The large conical papilla had a round base and a blunt tip without any projection. Two types of lenticular papillae could be distinguished. The irregular surface of all types of papillae revealed microplicae in the form of microridges and micropits. The fungiform papilla was studded with microvilli. The taste pores were oriented on the dorso‐lateral surface of the vallate papilla.
Über die pränatale Entwicklung der Lamina epithelialis in der Phase der Vakuolisierung villärer Epithelzellen. Untersuchungen am Darm des Rindes (Bos primigenius taurus L., 1758)
Authors: Wille K.‐H. , Winkler Fr. 
Published: June 2007

SummaryThe development of the bovine small intestine was examined in 39 embryos and fetuses by light microscopic and transmission electron microscopic methods. Special reference was paid to the histogenesis of the ephithelium.In contrast to the duodenum the epithelium of jejunum and ileum undergoes a degeneration by vacuolation of its villous epithelial cells. The demonstration of the acid phosphatase activity of these vacuoles shows their lysosomal character. This degenerative process of the small intestinal epithelium is also known in large intestine where it leads to the destruction of the intestinal villi. Both seem to be part of a ‘principle of construction of the intestine of the vertebrates’(Wille, 1984).

Authors: Dall'Aglio C. , Scocco P. , Ceccarelli P. , Pedini V. 
Published: June 2007

SummaryThe presence and the distribution of neuroendocrine cells in the gastrointestinal tract of adult wild boar were investigated. The endocrine cells have been identified by means of immunocytochemical techniques using antibodies against serotonin, gastrin, somatostatin, cholecystokinin (CCK), met‐enkephalin (MET‐ENK), gastric‐inhibitory peptide (GIP) and glucagon. The number of positive cells for each antiserum in each region was evaluated. Results were compared with data present in the literature and obtained previously by us and other authors in swine and domestic mammals (Ceccarelli et al., 1985, 1987, 1990, 1991, 1995; Capella and Solcia, 1972; Domeneghini and Castaldo, 1981; Peranzi and Lehy, 1984; Krause et al., 1985).
A Scanning and Immunohistochemical Study in Bovine Haemal Node
Authors: Cerutti P. , Marcaccini A. , Guerrero F. 
Published: June 2007

SummaryThe bovine haemal nodes are lymphatic organs with haemal circulation. The blood circulates inside of them through virtual cavities named sinuses. In these sinuses there is passage of cells and particulate materials from parenchyma to sinuses and vice versa. For this passage temporal overtures exist in the sinus walls. The sinus wall is composed of endothelial cells, basal membrane and reticular cells. Our results have demostrated that type IV collagen was one of the basal membrane constituents in bovine haemal nodes and by this constitution a dynamic equilibrium of the sinus walls was permitted.
3‐D Confocal Laser Scanning Microscopy used in Morphometric Analysis of Rat Purkinje Cell Dendritic Spines after Chronic Ethanol Consumption
Authors: Wenisch S. , Fortmann B. , Steinmetz T. , Kriete A. , Leiser R. , Bitsch I. 
Published: June 2007

SummaryA confocal laser scanning microscope (with a 543 nm laser) was used for imaging rat Purkinje cell dendritic spines at high 3‐D resolution. In a nutritionally controlled study of the rat, 5 months of ethanol consumption was demonstrated to alter the spines of Purkinje cell dendrites in rat cerebellum. Intact spines showed significant elongation after ethanol exposure, whereas this neuromorphological alteration could not be detected in controls. Spine elongation could be regarded as compensative growth of spines in search of new synaptic contacts due to alcohol induced cell loss.
Autoimmune Aspects of Three Skin Diseases: Pemphigus, Cutaneous Lupus Erythematosus and Vitiligo1
Authors: Mackay Ian E. 
Published: June 2007

SummaryThis paper discusses three skin diseases due to or associated with autoimmunity: pemphigus vulgaris, cutaneous lupus erythematosus and vitiligo.In pemphigus vulgaris there is an autoantibody to an. antigen in. the inter‐epithelial or cell‐wall region of the prickle‐cell layer of stratified squamous epithelium. The site of reaction of this antibody corresponds with the acantholytic lesions of pemphigus vulgaris.In cutaneous lupus erythematosus antinuclear antibody may enter mildly damaged cells of stratified squamous epithelium and react with the cell nucleus. This results in the formation and deposition of antigen‐antibody complexes at the dermal‐epidermal junction, and these complexes may be distributed systemically and trapped in the kidney, causing glomerulonephritis. Thus the skin could be a site of primary importance in the genesis of the systemic lesions of lupus erythematosus.Vitiligo is known to coexist with a group of diseases which are clinically and serologically interrelated and are attributable to autoimmunity: pernicious anaemia, Hashimoto's thyroiditis and thyrotoxicosis, and adrenal atrophy. Striking clinical examples of these associations exist, but no specific autoantibody system is demonstrable. Hence the case for autoimmunity in vitiligo rests only on “guilt by association”.
Pili Annulati*
Authors: Musso L. A. 
Published: June 2007

SUMMARYThe chance seeing of a case of pili annulati provided an occasion for reviewing the salient features of this condition. Previous observation that the abnormal areas disappear after exposure to weak alkali on a glass microscopic slide was confirmed.Electron microscopic examination of hair samples from the young man and his elder sister suggests that there is a primary defect in the synthesis of the microfibril + matrix complex with possibly less of it being formed and thus creating a potential space. The process appears to be intracellular.The gas in the canals or spaces is likely to be air due to the fact that hair fibres are relatively permeable to most gases and liquids.
Circumscribed Palmoplantar Keratoderma
Authors: Callan Noel J. 
Published: June 2007

SUMMARYA case of focal tender thickening of the palms and soles, with associated abnormalities of the cornea, is described. It is believed to be an example of circumscribed palmo‐plantar keratoderma, of autosomal recessive inheritance. Possible mechanisms involved in the production of the lesions are considered, and an approach to treatment discussed.

Published: June 2007

SUMMARYApocrine cystadenoma presents another distinct clinico‐pathological entity among the appendage tumours. Clinically these small skin coloured, blue or black cysts can usually be distinguished from basal cell carcinoma, melanocytic naevus, or a vascular lesion provided the possible diagnosis is borne in mind.Histologically the picture is quite distinct and diagnostic.
Microsporum Distortum Ringworm in New Zealand
Authors: Smith John M. B. 
Published: June 2007

SUMMARYThe dermatophyte Microsporum distortum has been recovered from 32 human infections and 7 animals in New Zealand. All cases have occurred within a limited rural area of the Otago province. A comparison of clinical and epidemiological characteristics of M. distortum ringworm with those of Microsporum canis reveals a close similarity between the two fungi. Both show a predilection for the scalp area and have similar age, sex and seasonal distributions. Cats seem to be the main source of human infection, but with M. distortum it is possible that these animals serve merely as a vector between man and some hitherto unidentified (wild) animal reservoir.

Published: June 2007

SUMMARYNatural infection of a red kangaroo (Megaleia rufa) with molluscum contagiosum pox‐virus is reported. Large lesions up to 2 cm diameter were present on the back, elbow and lip. Histopathology and electron‐microscopy confirmed that the disease was identical to human molluscum contagiosum.
EPIDERMOLYSIS BULLOSA—NEW THERAPEUTIC APPROACHES
Authors: Eisenberg M. , Stevens L. H. , Schofield P. J. 
Published: June 2007

SummaryDrug therapy of epidermolysis bullosa dystrophica (E.B.D.) for the past forty years is reviewed.A reproducible method for the direct extraction of collagenase and collagen peptidase from skin homogenates is described.Markedly elevated collagenase and collagen peptidase activity is demonstrated in skin of dystrophic E.B. patients. Diphenylhydantoin in pharmacological doses is shown to cause significant inhibition of the collagenolytic system both in vitro and in vivo. Diphenylhydantoin was used parenterally in two children with proven E.B.D. and was found to have a beneficial effect on skin fragility.
MALIGNANT MELANOMA IN QUEENSLAND A REVIEW
Authors: Davis Neville C. 
Published: June 2007

SummaryA study into malignant melanoma in Queensland commenced in 1963 and the findings are reviewed and the attitudes to management explained. The incidence of the disease is higher in Queensland than anywhere else in the world. This probably results from the long continued exposure of a susceptible white population to sunlight.Patients with suspected melanomas should be referred for definitive surgical treatment without preliminary biopsy. Local surgical treatment usually necessitates a wide excision and split skin graft. Routine elective lymphadenectomy is not indicated. The outlook for patients with melanoma is remarkably good in Queensland. There is an age‐adjusted cumulative five‐year survival of 87.7% for women and 73.6% for men. The treatment of patients with advanced or recurrent melanomas should be carried out in special clinics.
NOMA: REPORT OF THREE ADULT CASES*
Authors: Bendl B. J. , Padmos A. , Harder E. J. , McArthur P. D. 
Published: June 2007

SummaryThe case histories of three adult patients are presented. Malignant disease was present in all three. During the course of investigation and treatment one patient was found to have a lymphoma, another to have polymorphic reticulosis and the third had been under treatment for chronic myeloid leukaemia. The possible aetiological factors responsible for this clinical syndrome are discussed.
AUSTRALIAN ABORIGINES AND PSORIASIS
Authors: Green Allen C. 
Published: June 2007

SUMMARYPsoriasis among full‐blood Australian Aborigines appears to be rare or absent. After examination of some three thousand of these people in central, northern, and southern Australia, I have not seen psoriasis. Other medical and nursing observers have also not seen psoriasis in these people. Two references in the literature to psoriasis in Abotigines are reviewed briegly. The author has seen only one, male, part‐Aborigine (more Causcasian than Aborigine), with in a female Aborigine whose father was said to be “not tribal”. A third was recently reported to me.Other conditions common among Aborigines, which should not be confused with psoriasis, are outlined, Certain aspects of the apparent absence of psoriasis in full‐blood Australian Aborigines are discussed.Previous research about the essential causes of psoriasis has not been particularly rewarding. An important question must, therefore, be asked. Should some research projects in future be directed to reasons why some human groups seem not to get psoriasis rather than to why others do?

SUMMARYSporothrix schenckii is a fungus which occurs in soil and on plant material. It has not often been reported in Australia from clinical sources. Most reports have been from Queensland, and it has rarely been reported from the Sydney and Newcastle Metropolitan areas. Twelve isolations from the Sydney area are reported.
HUMAN INFECTIONS DUE TO TRICHOPHYTON EQUINUM VAR. AUTOTROPHICUM IN VICTORIA
Authors: Maslen Mary , Thompson P. G. 
Published: June 2007

SUMMARYTwo cases of human ringworm caused by the dermatophyte Trichophyton equinum var. autotrophicum are reported from victoria. This fungus has been recorded as a cause of ringworm in horses in Australia but infections in man are rare and this is the first report giving details of human infections in Australia. In one of these cases the fungus was also isolated from the patient's horse. Treatment with econazole nitrate was successful in this case.
THE MALIGNANT POTENTIAL OF PAPILLOMAVIRUS *
Authors: Dyall‐Smith Delwyn , Varigos George 
Published: June 2007

SUMMARYPapillomaviruses are double‐stranded DNA viruses which can be classified into groups, types and subtypes on the basis of DNA cross‐hybridisation and restriction endonuclease patterns. In the majority of cases they produce a benign epithelial proliferation. However, restricted types can be associated with malignant transformation. Persistent papillomas in rabbits and oesophageal papillomas in immunosuppressed cattle develop into carcinomas. Human papillomavirus (HPV) is associated with cervical and laryngeal carcinomas. Immunosuppressed patients and those suffering from the rare autosomal recessive disease epidermodysplasia verruciformis have an increased incidence of papillomas andsquamous cell carcinomas (SCC) on sun‐exposed areas. The DNA of HPV types 5, 8 and 14 can be found in these SCC and in their rare metastases. Generally the SCC can be related to a previous wart and occur on sun‐exposed areas. The mechanism of tumour induction is not clear. There is no evidence for cell transformation by integration of a viral promoter in front of a cellular oncogene. The viral DNA remains extrachromosomal without major deletions or insertions. Viral papillomas undergoing malignant transformation on the skin require the addition of ultraviolet light for successful transformation. UVB is known to disrupt DNA, impair Langerhans cell number and function and, in mice, induce a subset of suppressor T cells which enhance the occurrence of cutaneous malignancy. This suggests a viral mutation and/or local immunosuppression in the transformation mechanism. Research on papillomavirus is greatly hindered by the inability to culture virions. This is probably related to difficulty producing fully differentiated keratinocytes in culture as well as the prolonged incubation period of the virus.
RECURRING DIGITAL FIBROMAS OF INFANCY *
Authors: Ryman William , Bale Patricia 
Published: June 2007

SUMMARYRecurring digital fibromas are distinguished by their occurrence in infants, their almost exclusive predilection for the fingers and toes, their tendency to recur and their characteristic inclusion bodies.At the Royal Alexandra Hospital for Children (RAHC) thirty cases were seen in thirty‐six years. The patients were twenty females and ten males, aged 0–7 years, including two with congenital lesions. The fingers and toes were equally affected, and one unusual case involved the side of the hand. Multiple lesions occurred in 50% of patients, more often on the fingers, especially on adjacent fingers (six cases) and two patients had bilateral lesions. Although some lesions had infiltrated down to the periosteum, no metastases occurred in our series, or in the cases in the literature. As growth rate may be alarming, some of these tumours have been treated aggressively, but evidence suggests that a conservative approach should be followed.
