    Characterization of dopamine receptors involved in central thermoregulation in rabbits.
    (1991-11-01) Srivastava, A K; Srivastava, Y P; Gupta, P P; Verma, R B
    Intracerebroventricularly administered dopamine produced dose dependent hyperthermia in rabbits. Haloperidol, a D1 receptor blocker produced consistent hypothermia, whereas D2 receptor blocker metoclopramide produced hyperthermia, pretreatment with haloperidol competitively blocked the hyperthermic response of dopamine. Pretreatment with metoclopramide augmented the onset and peak response of dopamine. It is suggested that D1 receptors are involved in producing hyperthermia and D2 receptors in hypothermia.

    Knowledge About Sandflies in Relation to Public and Domestic Control Activities of Kala-azar in Rural Endemic Areas of Bihar.
    (2009-06) Kumar, Narendra; Siddiqui, N A; Verma, R B; Das, P
    Visceral Leishmaniasis (VL) control is a global cause of concern. To identify the gaps in People's knowledge/ awareness about sand flies and control activities of kala-azar in rural endemic areas of Bihar, this study consisting of 450 respondents with 288 male and 162 female was carried out. The result showed that 95% respondents had heard about the disease up to some extent, but majority respondents were neither aware about the vector of kala-azar, nor they had any idea about transmission of the disease. About 61% had wrong impression that mosquitoes were causing kala-azar. Regarding knowledge about breeding and resting sites of vectors, 20% reported cattle shed, 16% crevices in the household followed by 15% damp dark places. The attitude of respondents towards vector control programme was poor, as 99% lost faith in the DDT spraying because of ineffectiveness, like no reduction in mosquito nuisance. Bed net was considered the best protection method against sand fly or mosquito nuisance but the cost was considered the major constraint in its use. Proper health education programme in Simple and local language along with visual demonstration should be promoted to enhance the awareness and co-operation at community level.

    A pilot study on the status of lymphatic filariasis in a rural community of Bihar.
    (2006-03-21) Das, V N R; Siddiqui, N A; Kumar, N; Verma, N; Verma, R B; Dinesh, D S; Kar, S K; Das, P
    A pilot study of lymphatic filariasis was conducted in two contiguous villages of Patna district in Bihar situated at the side of the river Ganges, known to be endemic for lymphatic filariasis, to study present status of transmission parameters of filariasis. Of the 1872 persons examined, 8.4% were found asymptomatic but microfilaraemic. Morbidity pattern due to filarial infection showed an increase with advancement of age and significantly high in males as compared to female (p < 0.001). Acute and chronic filarial disease was observed as 0.5% and 9% respectively. Microfilaria was found in 10% of acute and 11.2% of chronic filarial cases. The Mf rate was found to be 9.9% in males and 9.0% in females respectively. The parasite species was identified as W. bancrofti. The vector fauna surveyed show highest prevalence of vector species of Cx. quinquefasciatus (43%) in both domestic as well as predomestic area in the community. Other species like Cx. vishnui and Ma. uniformis were also seen. Each household and predomestic area was searched for mosquito fauna at night. The infection rate in vectors was found to be 14% and infectivity rate (L3) was 8%. The filariasis cases detected in the study were treated with 12 days course of DEC 6 mg/kg body weight.

    Surveillance of drug induced diseases in children.
    (1994-07-01) Kushwaha, K P; Verma, R B; Singh, Y D; Rathi, A K
    A hospital based prospective study on drug induced diseases (DID) in children below 14 years of age was done for a duration of two years. A total number of 20,310 patients were examined in pediatric department during this period, out of which 204 (1.004%) patients were diagnosed as DID. Children with severe reactions were admitted in pediatric ward for in hospital intensive surveillance. The male:female ratio in DID was 1.2:1. DID were most common in neonates (24.51%). Erythmatous maculopapular rashes (67.12%) formed the most common pool of DID in neonates. Thrombophlebitis (41.56%) was most commonly seen in infants above 28 days of life, and in children up to 14 years of age. Out of 204 cases of DID, 9 (4.41%) died. Aplastic anemia was most morbid DID, as all the 7 patients of aplastic anemia died. Chloramphenicol was responsible for all the cases of aplastic anemia. Other two deaths were from erythma multiforme and C.C.F. The most commonly involved drugs, other substances and vaccines were baby powders, massage oils, ampicillin, co-trimoxazole, i.v. infusions (electrolytes and mannitol), DPT and measles vaccines.

    Urinary indican in healthy Indian subjects.
    (1977-10-01) Sharma, S K; Patney, N L; Mehrotra, M P; Verma, R B; Kumar, A
    Forty normal subjects have been taken for the present study. The mean Indican excretion was 40.45 mg/24 hrs. The mean jejunal count was 1.96 x 10(3) +/- 5.39 x 10(3) organisms/ml and 40% of the jejunal aspirates were sterile. Wide range of bacteria were cultured bu the coliform organisms were obtained in only 16.6%. There was a significant correlation between Indican excretion and total bacterial count (P less than .01).
