EFFECTS OF GLUCAGON ON HEMODINAMIC VARIABLES IN CONDITIONS ON BLOCADE BETA ADRENORECEPTORS

Scientific research of effects of glucagon on the cardiovascular system have shown that glucagon has some
cardiostimulatory potential. The very interesting fact is that glucagon shows its cardiostimulatory effects by activating its
own, higly specific glucagonic receptors. That is way we wanted to research not only the effects of glucagon on the C.V.S.
but also its effects during the depression of the C.V.S. with high dosses of beta blocators (presolol) expecting a good
hemodinamic response. The experiment has been performed on two groups of 6 dogs. The first group of animal was treated
with i.v. bolus injections of glucagon and other group with presolol (15 mg/kg b.w.) i.v., and after that with i.v. bolus
injection of glucagon. Hemodinamic variables (mean arterial pressure, central venal pressure and hearth frequency) were
registred at the 1-st, 2-nd, 3-rd, 10-th, 20-th, 30-th and 40-th minute. The hearth frequency was registred by continous
monitoring, mean arterial pressure was registred with cateter in the arterial femoralis, while the central venal pressure was
registred over central venal cateter in v. femoralis. After the i.v. bolus injection glukagon shows higly positive effects,
followed by short-term increase of the mean arterial pressure, while the c.v.p. considerably falls. During the administration
of presolol the hearth frequency and mean arterial pressure fall considerably and progressively, while the c.v.p. rises
considerably. Glucagon, in conditions of c.v.s. depresion by high doses of presolol (15 mg /kg b.w.) considerably increases
hearth frequency and mean arterial pressure, while the c.v.p. falls considerably.

ANTIPYRETICAL EFFECT OF PARSLEY EXTRACTS (Petroselinum crispum L.) AT MICE

With this work we intended to examine antipyretical effect of different extracts from the leaf. The following extracts were examined: etherical chloroformic The experiments were conducted on white laboratory mice, type BALB/C. Mice were divided in 5 groups, where each group received the appropriate extract. Rectal temperature was measured by "Termistorowy" termometer. After the temperatures were measured, for each of examined group we defined area under the curve. The area values were later used to determine statistically significant differences between them. Examination results of antipyretic effects of different extracts ( ) from the leaf, i parsley (Et O), (CHCl ), ethyl-acetic (EtOAC), n-bhutanolic (nBuOH), aquae- 2 3 ous (H O). 2 etherical (Et O), chloroformic (CHCl ), ethyl-acetic (EtOAC), n-bhutanolic (nBuOH), aquaeous (H O) parsley 2 3 2 n experiment with mice, show that all the extracts mentioned above, decreased (annuled) pyrogenic effect of 12% yeast suspension.
