A study of peripheral neuropathy in cases of type-II diabetes mellitus patients with or without hypothyroidism

Background: Type 2 diabetic patients have a higher prevalence of thyroid disorders, particularly hypothyroidism.  Peripheral neuropathy is a common and disabling complication of diabetes mellitus. Peripheral nervous system involvement in hypothyroidism is also a well-documented fact. Nerve conduction studies are generally considered to be the most sensitive and reproducible in the assessment of peripheral neuropathies. This study helped to determine the prevalence of peripheral neuropathy in diabetic hypothyroid patients as well as to compare it in diabetic patients with or without hypothyroidism. It compared the onset latency, amplitude, conduction velocity and F- wave latency of some nerves in type 2 diabetes mellitus patients with or without hypothyroidism.Methods: With RMS, EMG, EP MARK-II, nerve conduction studies are done in 30 cases (type 2 diabetes mellitus patients with hypothyroidism) and 30 controls (type 2 diabetes mellitus patients of diabetes without hypothyroidism) respectively, attending the Diabetic Clinic and Biochemistry Laboratory of North Bengal Medical College.Results: Data were treated with Unpaired t-Test. The study reveals that type 2 diabetes mellitus patients with hypothyroidism have higher prevalence of peripheral neuropathy. There is statistically significant (p<0.00) decrease in motor nerve conduction study in both right and left median nerves in diabetic patients with hypothyroidism than in diabetic patients without hypothyroidism.Conclusions: All diabetic patients should be screened for early detection of hypothyroidism as type 2 diabetic patients with hypothyroidism have higher prevalence of peripheral neuropathy. The nerve conduction study remains the most reliable, accurate, and sensitive method to evaluate peripheral nerve function

Alteration in behavior of rat after chronic exposure to acetamiprid

Background and Aim: Acetamiprid is a chemical of neonicotinoid group which binds with nicotinic acetylcholine receptor (nAChR) and alters the brain function. The present study was taken up to enlight the understanding of nociception behavior in Sprague Dawley (SD) rat after multiple exposures to acetamiprid. Materials and Methods: For experiment purpose, a total of 48 SD rats were divided into four dose groups having 12 animals each. Group I was control group received only distilled water. Group II, Group III, and Group IV were treated with acetamiprid at a dose rate of 5, 20, and 40 mg/kg body weight, respectively. Rats were tested in induced pain by formalin injection and tail flick test. Results: The flinch counts in formalin-induced pain in acetamiprid-treated rat were reduced in a dose-dependent manner, whereas, in tail flick test, no such altered pain behavior was observed in treated group compared to control animals. Conclusion: Acetamiprid alters the centralized nociception through nAChR but could not trigger the associated signal to inhibit the nociception peripherally

Development of nested polymerase chain reaction-based diagnosis of duck enteritis virus and detection of DNA polymerase gene from non-descriptive duck breeds of West Bengal, India

Aim: The study was undertaken to detect the clinical signs, postmortem lesions of embryonated duck plague (DP) infected eggs, and histopathological changes of chorioallantoic membrane (CAM) in non-descriptive ducks of West Bengal with special reference to standardize nested polymerase chain reaction (PCR). Materials and Methods: After postmortem of suspected carcasses, samples were collected for virus isolation and identification through specific pathogen free (Khaki Campbell) embryonated duck eggs. PCR was also done as confirmatory test after doing postmortem of duck embryos. DP specific nested PCR was standardized for better confirmation of the disease. Sensitivity of nested primers was also tested for DP virus. Results: Gross, postmortem and histopathological changes were prominent in dead embryos. First set of primer was able to detect 602 bp fragments of DNA polymerase gene of duck enteritis virus from infected CAM. Subsequently, a DP specific nested PCR which was very much sensitive for very small amount of viral genome was successfully standardized. After NCBI blast nucleotide sequence of nested PCR product (Accession No. HG425076) showed homology with the sequences data available in GenBank. Conclusion: The study concludes that PCR assay is very much helpful to diagnose DP disease and developed nested PCR is a double confirmatory diagnostic tool for DP
