Macrophage migration inhibitory factor is associated with mortality in cerebral malaria patients in India.

Background: Macrophage migration inhibitory factor (MIF) is a multifunctional cytokine implicated in the pathogenesis of a number of human diseases including inflammatory neurological diseases. Its role in the pathogenesis of cerebral malaria is unknown. Cerebral malaria is a life-threatening complication of falciparum malaria with approximately 20%-30% of patients dying despite appropriate anti-malarial treatment.

Intervention and prevention of hereditary hemolytic disorders in India: a case study of two ethnic communities of Sundargarh district in Orissa.

Objectives: This study was aimed at to sensitize, motivate, and screen two major vulnerable tribal communities--Bhuyan and Kharia, for hemoglobinopathies and allied hemolytic disorders, along with prospective and retrospective genetic/marriage counseling to the affected persons.

Characterization of ITS2 rDNA of Anopheles philippinensis and Anopheles nivipes (Diptera: Culicidae) from north-east India.

Anopheles (Cellia) philippinensis Ludlow and Anopheles (Cellia) nivipes (Theobald) are two closely related, morphologically very similar, mosquito species in the Annularis group, which play a supportive role in malaria transmission in north-east India. We amplified and performed sequence analysis for the internal transcribed spacer 2 (ITS2) locus of ribosomal DNA (rDNA) gene of morphologically confirmed specimens of these two species from the states of Assam and Nagaland. An.

Tobacco and alcohol use among the youth of the agricultural tea industry in Assam, India.

A cross-sectional study was conducted to assess tobacco use (both smoking and non-smoked tobacco) and alcohol use among tea garden youths of Assam, India during the period 2002-2003. A total of 650 tea plantation youth age 15-24 years (255 males, 395 females) from eight randomly selected tea plantations, Dibrugarh District, Assam, were interviewed to collect information on alcohol and tobacco use using a pre-designed, pre-tested questionnaire. Nearly 59% of the respondents had no formal education.

Correlates of alcohol consumption and tobacco use among tea industry workers of Assam.

Effects of verapamil and amiodarone on sympathoadrenal system and balance of excitatory and inhibitory amino acids in rat medulla oblongata.

Local injection of verapamil into ventrolateral region of the medulla oblongata triggered the release of epinephrine. Verapamil increased the total content of norepinephrine and epinephrine by 560% and decreased the content of serotonin by 46%. Verapamil had no effect on norepinephrine/epinephrine and norepinephrine/(norepinephrine+epinephrine) ratios in normal rats.

Effect of nonselective beta-adrenoblockers on the state of sympathoadrenal system and ratio of neuroactive amino acids in rat medulla oblongata.

Experiments on rats showed that injection of propranolol into the medulla oblongata increased the contents of epinephrine, norepinephrine, dopamine, and L-DOPA by 3.76, 1.4, 2.

Antiedematous and edematous effects of local anesthetic RU-353 applied to various regions of the medulla oblongata.

Experiments on random-bred albino rats showed that application of local anesthetic RU-353 to the dorsal nuclei of the vagus nerve produced edematous or antiedematous effects in the lungs. Our findings open new vistas in prevention of centrogenous forms of water imbalance in the lungs.

A rapid method to assess the coverage of the mass drug administration of diethylcarbamazine in the program to eliminate lymphatic filariasis in India.

A rapid method to assess the coverage of mass drug administration (MDA) in the program to eliminate lymphatic filariasis needs to be developed for monitoring and evaluation of the program. This study attempted to develop and test a method of rapid assessment of coverage by using the existing resources of the program. This is based on the data obtained from the randomly selected health workers and drug distributors involved in the drug distribution process and the data of a household coverage survey of the program.

Japanese encephalitis in Assam, northeast India.

Japanese encephalitis is one of the major public health problems in Assam, northeast India. We aimed to elucidated the clinical and epidemiological profile of the disease during several outbreaks in Assam in 3 consecutive years. Cerebro-spinal fluid and or serum samples of 348 out of 773 clinically-suspected viral encephalitis patients admitted to different hospitals during the period June to August of 2000 to 2002 were tested for detection of JE specific IgM antibody, employing MAC ELISA test at RMRC (ICMR), Dibrugarh.

Cure and reinfection patterns of geohelminthic infections after treatment in communities inhabiting the tropical rainforest of Assam, India.

Mass de-worming targeted at socio-economically poor communities can be considered as an option for communities living in the tropical forests of Assam who do not have access to safe drinking water and proper sanitation, and consequently have a higher risk of suffering from geohelminthic infection and associated morbidity. A random sample of 265 subjects was included in this study (134 males and 131 females). The chemotherapeutic regimen followed was a single dose of albendazole 400 mg.

To understand the possible origin of hepatitis B virus (HBV), three of the four hyperendemic, primitive accessible tribes of the Andaman and Nicobar islands, India, were investigated. The Nicobarese tribe was investigated in 1989 and 1999. The S gene from 65 HBV isolates was amplified by PCR and sequenced.

Leptospirosis disease burden estimation and surveillance networking in India.

Although leptospirosis is known to have occurred in India since the early years of the 20th century, no accurate data on disease burden exist. During the past two decades, leptospirosis cases have been reported with increasing frequency from different parts of the country. Several large outbreaks have occurred.

Molecular tools in leptospirosis diagnosis and characterization of isolates.

The incidence of leptospirosis in human beings has been increasing in recent years. Early diagnosis and treatment can prevent complications and reduce mortality. The conventional laboratory methods for diagnosis rely on the demonstration of leptospires in clinical specimens, recovering the organisms in culture or the demonstration of antibodies to leptospires.
