Assessment of community contribution to the ICDS scheme in district Agra: a case study

This study was conducted to assess community contribution to the Integrated Child Development Services (ICDS) program, which promotes mother and child health in the Agra district, Uttar Pradesh, India. Three rural ICDS projects in the district were selected, out of which a total of 74 Anganwadi centers (AWCs) were chosen for the study. The Anganwadi workers (AWWs) were interviewed through a semi-structured questionnaire to assess the community?s contribution during the previous 6 months. Results revealed that about 68% of AWWs had been able to receive assistance in bringing the children to the AWC. 53.3% had received free accommodation for AWC, and 42.6% had obtained assistance in implementation of health activities. Only 4% and 12% of the AWWs reported community assistance in the preparation and distribution of nutritional supplements, respectively. There had been no contribution received in terms of raw food for supplementary nutrition and fuel for cooking. The study concludes that rural area free accommodation for the AWC and community assistance in bringing children to the AWC were the most common forms of community contribution to the ICDS program.     

Design and synthesis of novel alpha(1)(a) adrenoceptor-selective antagonists. 1. Structure-activity relationship in dihydropyrimidinones

Dihydropyrimidinones such as compound 12 exhibited high binding affinity and subtype selectivity for the cloned human alpha(1a) receptor. Systematic modifications of 12 led to identification of highly potent and subtype-selective compounds such as (+)-30 and (+)-103, with high binding affinity (K(i) = 0.2 nM) for alpha(1a) receptor and greater than 1500-fold selectivity over alpha(1b) and alpha(1d) adrenoceptors. The compounds were found to be functional antagonists in human, rat, and dog prostate tissues. Compound (+)-103 exhibited excellent selectively to inhibit intraurethral pressure (IUP) as compared to lowering diastolic blood pressure (DBP) in mongrel dogs (K(b)(DBP)/K(b)(IUP) = 40) suggesting uroselectivity for alpha(1a)-selective compounds.     

Exposure to nicotine enhances acquisition of ethanol drinking by laboratory rats in a limited access paradigm

 Observations in humans suggest that the initial use of tobacco occurs in close temporal proximity to experimentation with alcohol. There have been relatively few research reports, however, examining possible interactions between these two agents. The present experiments examined the effect of nicotine exposure on the acquisition of ethanol drinking behavior in a limited access procedure. In experiment 1, rats were presented with 1-h access to ethanol solutions of increasing concentration for a period of 20 days. Subcutaneous injections of nicotine (0.6 or 1.2 mg/kg salt) or vehicle were administered 30 min prior to each ethanol presentation. Experiment 2 used a similar method, but rats were presented with water along with ethanol during the 1-h test session. Mecamylamine, a nicotinic receptor antagonist, was administered 30 min prior to the nicotine treatment. Nicotine was seen to produce a dose-dependent increase in ethanol drinking behavior which commenced at the 5% ethanol concentration and continued at 8% and again at 10%. In the second experiment, mecamylamine was observed to block completely the nicotine-induced increase in ethanol drinking behavior. The findings suggest that exposure to nicotine can facilitate the acquisition of ethanol drinking behavior in naive rats and that this effect is mediated by nicotine’s interaction at the nicotinic-cholinergic receptor.

Lichen dyschromicum perstans

A disorder of hyperpigmentation is described which is seen commonly in middle aged individuals. Face and neck including upper part of the trunk are mostly affected. The lesions are usually bilaterally symmetrical and occur in a localized or generalized distribution. Oral mucosa is infrequently involved. The colour of pigmentation varies from grey, blue and brown to black and it persists for years. None of the patients had any features of lichen planus. Histopathology reveals varying rates of lichenoid tissue reactions. We have tentatively designated this disorder as lichen dyschromicum perstans. Its relationship with other similar disorders is discussed.     

Disseminated and atypical molluscum contagiosum in an AIDS patient

A case of disseminated molluscum contagiosum (MC) has been reported in a patient suffering from AIDS. Most of the lesions were erythematous papules and nodules with central unbilication. A few giant lesions and lesions over genitalia were also observed.     

Prognostic Significance of Proliferating Cell Nuclear Antigen (PCNA) in Squamous Cell Carcinoma of the Esophagus

Proliferating cell nuclear antigen (PCNA) has been shown tobe of prognostic significance in some gastrointestinal tumors.Immunohistochemical analysis was performed to determine whetherPCNA is useful for predicting the outcome of patients with squamouscell carcinoma of the esophagus. Using a mouse monoclonal antibody,PC 10, the expression of PCNA was studied in resected squamouscell carcinomas of the esophagus from 59 patients who had undergonecurative esophagectomy. None had received any preceding therapy.The proliferation rate was assessed in terms of the percentageof the PCNA-positive nuclear area relative to the total areaof cancer nuclei using a cell analysis system (CAS). Clinicopathologicalvariables including PCNA staining were assessed in relationto prognosis. Survival rate was obtained by the Kaplan-Meiermethod. The PCNA indices (percentage of the positive nucleararea) of the tumors varied from 4.4% to 96.2%. Among the clinicopathologicalvariables, only tumor size (5 cm) and depth of invasion werecorrelated significantly with PCNA index (P<0.05). Microscopically,PCNA was stained in non-keratinized cells but not in keratinizedcells. However the histological grade was not correlated withPCNA index. The survival rate was significantly worse in patientswith high PCNA indices (40%) than in those with low indices(<40%) (P<0.05). However, multivariate analysis revealedthat PCNA index was not an independent prognostic factor.     

Seasonal variation of alkaloids of Adhatoda vasica and detection of glycosides and N-Oxides of vasicine and vasicinone

The distribution pattern of the alkaloids of A. Vasica has been studied with change of season. The study also resulted in the detection of glycosides and N-oxides of vasicine and vasicinone.     

Attenuation of voluntary ethanol consumption by dopamine-beta-hydroxylase inhibition (FLA-57): mediated by changes in aversion, reinforcement or both

The dopamine-beta-hydroxylase inhibitor, FLA-57, was reported by several investigators to reduce voluntary ethanol consumption in rats. The nature of the effect of FLA-57 on this behavior had been attributed to its involvement in both the mediation of positive reinforcing and aversive processes. In the present study, the capacity of FLA-57 to induce a conditioned taste aversion (CTA) in both a forward and a "nominally backward conditioning" paradigms was investigated. This was done in an attempt to assess the possible contribution of a FLA-57-induced CTA to the previously observed reduction in ethanol intake in several drinking studies. Furthermore, the ability of FLA-57 to induce a CTA in a nonnovel situation, where the taste of the presented solution (ethanol or saccharin) was familiar to the animals, was also assessed. The inclusion of these specific conditions was necessitated by the attempt to create conditions similar to those prevalent in drinking studies. We found that FLA-57, in both conditioning paradigms, induced a significant CTA. Animals, naive and experienced with the taste of ethanol or saccharin, exhibited a CTA following the administration of FLA-57. However, the magnitude and rate of extinction of the observed CTAs did not resemble those observed in studies on the effects of FLA-57 on ethanol intake. The results of this study suggest that while it is possible that FLA-57 exerts its effect on ethanol intake, at least in part, through an aversive mechanism, such a mechanism is unlikely to be the exclusive process through which ethanol ingestion is attenuated.
