BACKGROUND Genetic factors are known to be involved in oral squamous cell carcinoma (OSCC) development. METHOD We evaluated a possible association between CCND1 A870G and P21/WAF1 C98A polymorphisms and OSCC, as well as the impact of the genotypes on protein immunoexpression. The study group consisted of 80 individuals with histopathological diagnosis of(More)
A questionnaire addressing issues related to electroconvulsive therapy (ECT) was administered to 165 undergraduate medical students in an urban hospital in India. Of various sources, the mass media contributed most to the students' knowledge about and attitudes toward the treatment. Senior and junior students differed little in their knowledge and(More)
BR-16A is an herbal (non allopathic) medication used in India to enhance cognition. In experiment 1, 28 Wistar rats received either BR-16A (200 mg/kg/day) or vehicle alone for 3 weeks. During the third week, the rats were tested for learning in the Hebb Williams complex maze. BR-16A-treated rats showed significantly better learning than did controls.(More)
Forty nine adult male Sprague Dawley rats were selected for rapid learning in a T-maze to study the effects of BR-16A, a herbal preparation on ECS-induced retrograde amnesia. Half the rats received 200 mg/kg BR-16A and the other half received vehicle alone. The rats were trained to run into the enclosed chamber of either the left or the right arm on a(More)
To date, no pharmacological agent has been confirmed to lessen electroconvulsive therapy (ECT)-induced memory deficits. BR-16A is an herbal preparation, containing various organic extracts, used in India for the enhancement of cognition (among other applications). In the present study, adult male Sprague-Dawley rats received six once-daily electroconvulsive(More)
During the last decade the use of herbal medicinal substances in the attenuation of anterograde and retrograde amnesia induced by electroconvulsive shock (ECS) has been studied using animal research. We will discuss the background of herbal medicine in India, review the research findings on herbal medicines for ECS-induced amnestic deficits, and examine the(More)
Phenylephrine is a nonselective alpha-receptor agonist. This study examined whether the administration of phenylephrine immediately before electroconvulsive shocks (ECS) attenuated ECS-induced retrograde amnesia. Adult male Wistar rats received phenylephrine (0.25 mg/kg i.p.) or saline 3 min before each of three once-daily true or sham ECS. Retention of(More)
Study was conducted to find out the correlation between red blood cholinesterase (RBC ChE) and plasma butyryl cholinesterase (BuChE) activities and toxic signs of oral methylparathion (MPT) and their recovery pattern with or without atropine treatment in female rats. Enzyme activity was estimated before and after an oral dose of MPT (7.5 mg/kg-1) at various(More)
