EXHIBIT 31.1
            CERTIFICATION OF THE CHIEF EXECUTIVE OFFICER PURSUANT TO

SECTION 302 OF THE SARBANES-OXLEY ACT OF 2002

I, Peter Katevatis, Chief Executive Officer, certify that:

      (1)  I have reviewed this  quarterly  report on Form 10-QSB of Mediscience
           Technology Corp.;

      (2)  Based on my  knowledge,  this  report  does not  contain  any  untrue
           statement  of a  material  fact  or omit to  state  a  material  fact
           necessary to make the statements made, in light of the  circumstances
           under which such statements were made, not misleading with respect to
           the period covered by this report;

      (3)  Based on my knowledge, the financial statements,  and other financial
           information  included in this report,  fairly present in all material
           respects,  the financial  condition,  results of operations  and cash
           flows of the registrant as of, and for, the periods presented in this
           report;

      (4)  The registrant's other certifying  officers and I are responsible for
           establishing and maintaining  disclosure  controls and procedures (as
           defined  in  Exchange  Act Rules  13a-15(e)  and  15d-15(e))  for the
           registrant and have:

           a)   designed such disclosure controls and procedures, or caused such
                disclosure  controls  and  procedures  to be designed  under our
                supervision, to ensure that material information relating to the
                registrant,  including its  consolidated  subsidiaries,  is made
                known to us by others within those entities, particularly during
                the period in which this report is being prepared;

           b)   evaluated  the  effectiveness  of  the  registrant's  disclosure
                controls and procedures  and presented in this quarterly  report
                our  conclusions  about  the  effectiveness  of  the  disclosure
                controls and procedures,  as of the end of the period covered by
                this report based on such evaluation; and

           c)   disclosed in the report any change in the registrant's  internal
                control over financial  reporting  that has occurred  during the
                registrant's most recent fiscal quarter (the registrant's fourth
                fiscal  quarter  in the  case of the  annual  report)  that  has
                materially  affected,  or is  reasonably  likely  to  materially
                affect,   the  registrant's   internal  control  over  financial
                reporting; and

      (5)  The  registrant's  other  certifying  officers and I have  disclosed,
           based  on  our  most  recent  evaluation  of  internal  control  over
           financial  reporting,  to the  registrant's  auditors  and the  audit
           committee  of  the  registrant's   board  of  directors  (or  persons
           performing the equivalent functions):

           a)   all  significant  deficiencies  in the  design or  operation  of
                internal  control over financial  reporting which are reasonably
                likely to adversely affect the  registrant's  ability to record,
                process, summarize and report financial information; and

           b)   any fraud, whether or not material,  that involves management or
                other employees who have a significant  role in the registrant's
                internal control over financial reporting.
