Anti-inflammatory activity of flowers of Rhododendron arboreum (SMITH) in rats hind paw oedema induced by various phlogistic agents
SS Agarwal, Sharma Kalpana
April-June 1988, 20(2):86-89
1. The effect of various extracts of flowers of Rhododendron arboreum viz. aqueous, 50% ethanolic and methanolic extracts have been investigated against carrageenan. PG(E2). histamine and 5-HT induced rat's hind paw oedema. 2. The extracts exhibited significant anti-inflammatory activity against all the four phlogistic agents. Mean changes in the psw volumes revealed the efficacy of extracts against the four phlogistic agents in the following order : Carrageenan > 5-HT > PG(E2) > Histamine. 3. Among the three extracts tested. the acqueous extracts showed maximum anti-inflammatory activity followed by 50% ethanolic and methanolic extracts.

Mechanism of acute pressor response to cadmium chloride
R Balaraman, OD Gulati, JD Bhatt, SP Rathod, KG Hemavathi
April-June 1988, 20(2):67-74
1. In rats, acute I.V. administration of CdCl2 (0.5 and 1 mg/kg) produced a depressor response followed by a pressor response while the acute i.p. administration of CdC12 (0.5 and 1 mg/kg) produced only a pressor.response. 2. The blood pressure responses to a low dose of NA (0.5 (g/kg) was significantly reduced after the acute i.v. CdCI2( 1 mg/kg) administration while those to higher doses were not morliiied. 3. He amethonium (10 mg/kg. i.v.), phentolemine (5 mg/kg, i.v.). propranolol (2 mg/kg, i.v.) or indomethscin (20 mg/ kg i.p.) did not modify the pressor response to CdC12 (i.v. and i.p.). 4. Acute reserpinisation. bilateral adrenalectomy or chemical sympathectomy by guanethidine did not modify the acute pressor response to CdCl2 (i.v. and i.p.). 5. Verapemil(0.5, 1 and 2 mg/kg, i.v.) or nifedipine (0.25 and 0.5 mg/kg, i.v.) prevented the acute pressor response to CdC12 (i.v. and i.p.) 6. It s concluded that cadmium might mimic calcium ion and produce a direct contractile effect on the vascular smooth muscle.

Changes in plasma and brain tryptophan and serotonin levels following fenfluramine administration in rat
M Ani, A Boroumand-Naini
April-June 1988, 20(2):171-174
1. Fe nfluramine. on ( norexogenic drug, is believed to exert itr effectvia the serotonergic system et the level of hypothalamus. Since tryptophan is the precursor of serotonin. the effect of this drug on tryptophan metabolism in the rat was investigated. 2. Serum total tryptophan level increased transientlyfollowing fenfluramine administration (10 mg/kg) for 10 days returning to the normal level despite the continuation of the treatment for long period of time up to 45 days. Furthermore, the bound fraction of this amino acid was mainly effected end the free fraction remained unchanged. 3. Brain tryptophan rose in parallel with the serum level, whereas brain serotonin level showed a significant decrease after fenfluramine injection. 4. These results explain the transient action of fenfluramine in production of anorexia and bring further, evidence to support the view that serotonergic system is involved in the mechanism of action of this agent.

Pharmacological actions of vulpunic acid, a lichen metabolite
Rao AVN Appa, MC Prabhakar
April-June 1988, 20(2):143-151
1. Vulpinic acid (VA) isolated from the rare Himalayan Lichen Alectoris Virens exhibited hypotensive. anti-inflammatory. analgesic. anti-spasmodic (non-specific) and neuromuscular junction blocking properties. 2. Hypotensive effect of VA is attributed to its direct cardiac depressant action coupled with its property of: peripheral vasodilatation. 3. Anti-inflammatory effect of VA is attributed to its anti-histaminic and anti-serotonin properties. 4.The mechanism of action of VA at the neuromuscular junction appears to be complex.

Mechanism of noradrenaline release by histamine in the estrogen primed rat-uterus
RK Goyal, KC Dave
April-June 1988, 20(2):135-142
1. Histamine (9.7 X 10-7M - 2.3 X 1O-5M) produced a dose dependent relaxation of the estrogcn primed rat uterus. These reponses were significantly potantiated by nialamide (2.2 X 10-6M). pyrogallol (7.9 X 10-5 M) and desmathylimipramine (4.3 x 10-6 M). 2. Guansthidine (2.5 x 1D-6M) produced time dependent effect on histamine induced responses. The responses to histamine were significantly potentiated at the end of 10 min exposure to guanethidine However. after 30 min there was significant time-dependent inhibitinn of the responses to histamine. 3. The responses to histamine were inhibited significantly when NaCl concentration of the perfusion fluid (de-Jalon) was reduced to zero. Further. When Cacl 2 concentration (0.25 mM) in the NaCI free solution was increased to 1.0 mM. the responses to histamine were restored to the normal. 4 . Unlike that of histamine the absence of Nacl did not effect the responses to tyramine or isoprenaline in to rat uterus. 5. Our data suggest that the mechanism of release of noradrenaline in the rat uterus may be consequence of pre-synaptic H2 receptor stimulation.

Cholinergic effects of clonidine on the rat anococcygeus muscle preparation
SK Gohil, VK Patel, RV Bhatt, RK Goyal
April-June 1988, 20(2):159-166
1. The present Investigation was undertaken to study the cholinergic effects of clonidine on the isolated rat anococcygeus musIce. 2. Clonidine produced dose dependent contractions of rat anococcygeus muslce which were completely antagonised by phentolamine and atropine. 3. Sub-threshold dose of clonidine produced potentiation of carbachol and acetylcholine induced responses. but did not alter responses to noradrenaline dopamine or 5-hydroxytryptamine (5-HT). 4. Clonidine. however. failed to potentiate the carbachol induced responses on preparations which We re bathed with physiological salt solution containing low Ca++ low Na++ or niludipine. However the potentiation was maintained in PSS containing more Ca ++.yohimbine. prazosin or ouabain. 5. It is concluded that clonidine has indirect cholinomimetic effect, which involved extracellular sodium (NA+) and calcium (Ca++).

Influence of temperature on the status of histamine receptors in the isolated guinea pig ileum
PK Bhuttani, RJ Shah, KR Goyal
April-June 1988, 20(2):122-128
1. Histamine a non-specific H-receptor agonist & 2 (2-pyridyl) ethylamine (PEA).an H1 receptor agonist produced dose dependent contractions of guinea-pig ileum at 37". 25" and 15 C. 2. The responses were blocked competitively by mepyramine (1 X 10-9 M) at 37oC and 25 C. The antagonism appeared to be non-competitive at 15 C. 3. Ranitidine (1 X 10 -7M) inhibited the responses to histamine at all temperatures. 4. Dimaprit, a specific H2 receptor agonist did not produce any effect at 37C. However at 25C and 15C. it produced a dose dependent contraction and the responses were competitively blocked by rantidine. 5. Our data suggests decrease in H1-receptors and appearance of excitatory H2-receptors at lower temperatures in guinea pigileum. ,

Effects of metoclopramide and the status of dopamine receptors in rat anococcygeus muscle
VK Patel, RV Bhatt, KR Goyal
April-June 1988, 20(2):129-134
1. Dopamine produced a dose-dependent contraction of rat anococcygeus muscle. in the presence of sub-threshold dose of metoclopramide (2.8 x 1O-8 M), the responses to dopamina were potontiated. 2. Dopamineinduced contractions were competitively antagonized by haloperidol and phentolamine. Phentolamine induced inhibition of dopamine-receptors was partially uncovered by motociopramide. 3. Dopamine (1 X 10-10 M) inhibited there sponses to field stimulation which was prevented by metoclopramide. 4 . In the reserpinized anococcygeus muscle preparations the responses to dopamine were reduced significantly and metoclopramide failed to produce any potentiation of the responses. 5. The data presented suggest the presence of inhibitory presynaptic dopamino receptors in the rat anococcygeus muscle that are specifically antagonized by metoclopramide.
