Antihistaminics are widely used for various indications during microbial infection. Hence, this paper investigates the antimicrobial activities of 10 antihistaminics belonging to both old and new generations using multiresistant Gram-positive and Gram-negative clinical isolates. The bacteriostatic activity of antihistaminics was investigated by determining their MIC both by broth and agar dilut...

Under certain circumstances injected inosine causes a net vasoconstrictive effect on the arterioles, which has been attributed to 5-hydroxytryptamine (5HT) released in response to adenosine type 3 (A(3)) receptor stimulation of mast cells residing in the adventitia. We have sought further evidence for this hypothesis using blood vessels of the rat hind limb perfused in vitro at constant rate wi...

A haemorrhagic protein toxin (SA-HT) was isolated and purified from the spine extract of the Indian venomous butterfish, S. argus Linn, by two step ion exchange chromatography. The toxin was homogeneous in native and SDS-PAGE gel. SDS-molecular weight of the toxin was found to be 18.1 +/- 0.09 kDa. SA-HT produced severe haemorrhage on stomach wall but devoid of cutaneous haemorrhage. UV, EDTA, ...

Clozapine has been consistently shown to be superior to other antipsychotics in the treatment of psychosis. However, clozapine usage has been limited due to required routine blood monitoring and the potential for life threatening side effects. We report a case of a 66-year-old female patient, who developed clozapine-induced agranulocytosis after 10 weeks of clozapine treatment and was subsequen...

Hyperphagia was induced in mice by p.o. administration of different types of CNS depressant drugs, like chlordiazepoxide 25 mg/kg diazepam 2.5 mg/kg, cyproheptadine 2 mg/kg and phenobarbitone 25 mg/kg. Such hyperphagia was abolished by pretreatment with naloxone 0.1 mg/kg sc. Naloxone per se at this dose produced no significant effect on the food intake. This is suggestive of the role of peptid...

BACKGROUND Children with cancer frequently have associated cachexia and malnutrition. Failure to thrive affects nearly 40% of oncology patients with advanced or progressive disease. Malnutrition can erode quality of life and adversely impact disease prognosis. Appetite stimulation and increased food intake is 1 approach to combat cancer-related cachexia. MATERIALS AND METHODS Cyproheptadine h...

This case report discusses the history and management of a schizophrenic patient, a 18-year-old man, who had taken a massive overdose of clonazepam, abilify, depakote, zoloft and seroquel altogether. After discontinuation of these drugs and administration of cyproheptadine with IV fluids, he became hemodynamically stable. This case suggests that serotonin syndrome should be recognized promptly ...
