Clinicomicrobiological study of chronic paronychia
Guha P,Panja S
Indian Journal of Dermatology, Venereology and Leprology , 1992,
Abstract: A total of 261 digits affected in 100 patients of chronic paronychia were studied for clinical features. The bacteriological and mycological flora have been examined in 25 cases of the above 100 cases which were most severely affected. Aerobic bacteria were found in all cases. Staphylococcus aureus was seen in 60 percent. Klebsiella in 16 percent, Escherichia coli in 12 percent, Pseudomonas aeruginosa in 12 percent, Proteus mirabillis in 8 percent, Staphylococcus epidermidis in 4 percent and Streptococcus viridans in 4 percent. Culture for fungus revealed Candida albicans in 64 percent and other species such as C. krusei, C. stellatoides, C. viswanathi, C. parapsilosis and C. tropicalis were present in 1 case each. No fungus was detected in 4 cases(16percent). The present investigation was designed to compare the bacterial and mycotic flora of the nail folds of patients of chronic paronychia with that of western countries.

An Evaluation Of Acupuncture As A Modality Of Treatment Of Leprous Neuritis
Chattopadhyay S P,Neogi Bidisa Guha
Indian Journal of Dermatology , 1995,
Abstract: Eighty patients of leprosy who developed peripheral neuritis as a presenting feature or during the course of antileprotic trearment were selected for the study. Groups 1,2,3(N= 20 each) were given acupuncture therapy and considered as acupuncture group . Twenty patients were used as control (Group 4). Patients in acupuncture group showed improvement in subsidence of neural plain and tenderness after ten sittings of acupuncture. The response was best when acupuncture was given as adjunct to antireaction drugs. Relapse rates in Gr. 1, 2, 3 and 4 were 20, 30, 10 and 40 percents respectively. However the effect of acupuncture was temporary and on statistical analysis it was not considered significant when taken as a whole (acupuncture group). Hence acupunture is only recommended where corti- costeroids/NSAIDS are contraindicated. In view of AIDS and Hepatitis B infection, all cases are advised to be screened before acupuncture therapy and the acupuncture needles are autoclaved.
Progressive cardiomyopathic lentigenosis
Guha P,Barbhuiya J,Maity S
Indian Journal of Dermatology, Venereology and Leprology , 1991,
Abstract: A new case of progressive cardiomyopathic lentigenosis is presented. The major feature of this patient are cutaneous abnormality, hypertrophic cardiomyopathy, cephalofacial dysmorphism, short stature and recurrent epistaxis.
Aegle Marmelos Enhances Gastric Mucosal Protection: Relevance for NSAIDS-Induced Gastric Mucosal Injury
Al Ameen Journal of Medical Sciences , 2012,
Abstract: Objective: In order to study the gastroprotective effect of Aegle marmelos extract (AM), this study was undertaken on aspirin-induced ulcerogenesis in cannulated free-moving rats. Background: Most of the non-steroidal anti-inflammatory drugs (NSAIDs) including aspirin (ASP) cause gastric ulcer. The efficacy of several plants for the treatment of gastroduodenal disease is confirmed by clinical research, while basic scientific research helps us to uncover the mechanisms by which these plants exert their therapeutic effects. Method: To assess the possible antiulcer effect of AM, lesion index, gastric secretions glycoprotein levels and mucosal histopathology were determined in ASP induced gastric mucosal injury in cannulated free-moving rats. Results: Pretreatment with AM significantly prevented the development of gastric mucosal lesion and decreased the gastric toxicity produced by ulcerogen. In addition, ulcerated rats showed depletion of gastric wall mucus, glycoproteins and enhanced gastric acid secretion whereas treatment with AM prevented these ASP induced responses in cannulated free-moving rats. Histological studies confirmed the results. Conclusion: The present finding suggests that AM promotes ulcer protection by the decrease in ulcer index, gastric secretions and increase in the glycoprotein level, gastric mucin content and maintenance of mucosal epithelium. AM protects the gastric mucosa against ulceration by its antisecretory and cytoprotective property.
Primary systemic amyloidosis, presenting as periorbital pigmentation
Barbhuiya J,Guha P,Dutta B
Indian Journal of Dermatology, Venereology and Leprology , 1994,
Abstract: A case of primary systemic amyloidosis with periorbital pigmentation is reported. She had muscular weakness, weight loss, paresthesia of hand, hoarseness, oedema, dyspnoea, macroglossia, dysphagia &purpura. There was extreme fragility of both involved or non-involved skin. Fat aspirate from abdominal subcutaneous tissue was positive for amyloid.
On Quantized Lienard Oscillator and Momentum Dependent Mass
B. Bagchi,A. Ghose Choudhury,P. Guha
Physics , 2013,
Abstract: We examine the analytical structure of the nonlinear Lienard oscillator and show that it is a bi-Hamiltonian system depending upon the choice of the coupling parameters. While one has been recently studied in the context of a quantized momentum- dependent mass system, the other Hamiltonian also reflects a similar feature in the mass function and also depicts an isotonic character. We solve for such a Hamiltonian and give the complete solution in terms of a confluent hypergeometric function.
A study of two new generalized negative KdV type equations
Partha Guha,P G L Leach
Physics , 2014,
Abstract: We give a simple geometric interpretation of the mapping of the negative KdV equation as proposed by Qiao and Li {arXiv:1101.1605 [math-ph], Europhys. Lett.,94 (2011) 50003} and the Fuchssteiner equation using geometry of projective connection on S1 or stabilizer set of the Virasoro orbit. We propose a similar connection between with the higher-order negative KdV equations of Fuchssteiner type described as and respectively. We study the Painleve and symmetry analyses of these newly found equations and show that they yield soliton solutions.
Strong cation exchange resin for improving physicochemical properties and sustaining release of ranitidine hydrochloride
Khan S,Guha A,Yeole P,Katariya P
Indian Journal of Pharmaceutical Sciences , 2007,
Abstract: In the present study strong cation exchange resin (Amberlite IRP69) was used to improve the physicochemical properties of ranitidine hydrochloride such as taste and bulk properties and to sustain dissolution rate. Drug-resin complexes were prepared using batch method. Drug loading was done under different processing conditions such as temperature, pH, drug-resin ratio, and drug concentration to get the optimum condition for resinate preparation. Resinate prepared under optimized condition was tested for taste, bulk properties and release rate. Degree of bitterness of ranitidine was found to reduce to zero after complexation with resin. Improvement in flow properties was also observed. Angle of repose for resinate was found to be 33.21 o as compared to 42.27 o for ranitidine HCl. Effect of dissolution medium and particle size on in vitro release of drug from resinate was also investigated. Resinate with drug to resin ratio of 2:3 and particle size> 90 μm showed about 90% of drug release within 12 h. The orodispersible tablet formulated from the resinate containing 10% croscarmellose sodium disintegrated within 35 sec in oral cavity and showed similar dissolution profile as the resinate. Tablets were found stable after stability studies with no change in dissolution profile.
