Conclusions Limitation of this analysis is participation of limited centers. Though all the regions of the country are represented total
number of procedures reported are less. Isolated CABG is commonest procedure performed in 2004. Congenital surgical procedures
are more than the valvular heart disease procedure. For appropriate categorization we need standard nomenclature for various
congenital surgical procedures. 相似文献
The organisation and management of a cancer detection camp in rural area of Andhra Pradesh with the help of Lions Club and medical college staff were described. People with any one of the seven warning signals of cancer were asked to attend the camp. More women, most of them in reproductive age, attended the camp with unusual vaginal bleeding and lump in the breast. Among men, a large group complained of chronic cough. Smear for Papanicolaou's stain was used as a tool for screening of cervical cancer. Ten patients (2.5%) had malignant lesions and 16 patients (4.0%) had premalignant lesions. The programme of prevention, public health education and early detection of cancer can be put into action, successfully through cancer detection camps organised in rural areas. 相似文献
Guar gum-based three-layer matrix tablets of a highly water-soluble drug, trimetazidine dihydrochloride, were evaluated for their in vivo release in healthy volunteers in comparison with commercially available conventional immediate release tablets. Six healthy volunteers participated in the study and a two-way crossover design was followed. The plasma concentration of trimetazidine dihydrochloride was estimated by reverse-phase HPLC. The pharmacokinetic parameters were calculated from the plasma concentration of trimetazidine dihydrochloride versus time data. The delayed T(max), decreased C(max) and K(a), unaltered bioavailability, and prolonged t(1/2) and MRT indicated a slow and prolonged release of trimetazidine dihydrochloride from guar gum three-layer matrix tablets in comparison with the immediate release tablet dosage form. The guar gum three-layer matrix tablets of trimetazidine dihydrochloride may be useful in providing constant drug delivery with minimum fluctuations. 相似文献
The value of autopsy in understanding the natural course of any disease is beyond any argument. The reluctance of pathologists to perform autopsy in HIV infected cadavers is justified due to the risks involved to the prosector and the morgue attendants. A relative low risk needle necropsy protocol is proposed using fine needle aspiration cytology, tru-cut biopsies and microbiological examination. Diagnosis could be offered in all the forty-four needle necropsies performed. Disseminated tuberculosis in 18/44 (40.9%) cases, disseminated cryptococcosis in 12/44 (27.2%) cases, poly-microbial infections in 27.2% cases and non-Hodgkin's lymphoma in 9% cases were detected in the study. Infectious agents like Histoplasma capsulatum, Isospora belli, tachyzoites of Toxoplasma gondii, Candida sp and Cryptococcus sp could be demonstrated in the samples obtained in the study. Lack of material for study of gross pathology, inaccessibility of deep-seated lesions and risk of needle stick injury to the prosector though low are the limitations of this procedure. 相似文献
With the introduction of high-throughput sequencing methods, our understanding of the human lower respiratory tract's inhabitants has expanded significantly in recent years. What is now termed the “lung microbiome” has been described for healthy patients, as well as people with chronic lung diseases and lung transplants. The lung microbiome of lung transplant recipients (LTRs) has proven to be unique compared with nontransplant patients, with characteristic findings associated with disease states, such as pneumonia, acute rejection, and graft failure. In this review, we summarize the current understanding of the lung microbiome in LTRs, not only focusing on bacteria but also highlighting key findings of the viral and the fungal community. Based on our knowledge of the lung microbiome in LTRs, we propose multiple opportunities for clinical use of the microbiome to improve outcomes in this population. 相似文献
The influence of fluctuating water temperature and dietary oxytetracycline (OTC) at 0 (0X), 80 (1X), 240 (3X), 400 (5X) and 800 mg (10X)/kg biomass/day for 30 consecutive days on the safety of monosex (all male) Nile tilapia Oreochromis niloticus fries in terms of feeding, growth, survival and histopathology of vital organs were assessed. A dose-dependent decline in feed intake and biomass was recorded. The OTC-dosed groups recorded higher mortalities than the control. The therapeutic OTC-dosing (1X) in conjunction with low temperature caused 75.56 ± 8.01% mortality and 25.75% reduced feed intake in 30 days. The mortalities increased with increasing OTC-doses from 85.19 ± 3.39% (1X) to 95.56 ± 2.22% (10X) and fluctuating temperature (12.00–21.50°C) even after the withdrawal of OTC. Relatively mild to moderate histopathological lesions were observed in the kidney, liver and intestine of OTC-dosed fries. These results suggested that dietary OTC and low water temperature may cause adverse effects on monosex O. niloticus fries.
An enzyme which catalyzed the hydrolysis of crotoxyphos ((E)-1-phenylethyl 3-[(dimethoxyphosphinyl)oxy]-2-butenoate) was isolated from nonsterile and radiation-sterilized Chehalis clay loam with 1.5M Tris (2-(hydroxymethyl)-2-nitro-1,3-propanediol) and partially purified with lead acetate treatment. Two soil-g equivalents of lead acetate purified enzyme in pH 8 buffer hydrolyzed 0.13 mol of substrate to dimethyl phosphate and -methylbenzyl 3-hydroxycrotonate in 16 hr at 37°C. The enzyme exhibited maximal activity around pH 8.0 and was irreversibly inactivated below pH 5.0 or above pH 10.0. The Km value for crotoxyphos was calculated to be 4.63×10–3 M. The enzyme was stable at 60°C for 10 min, retained activity indefinitely at –10°C, and was completely inactivated within a week at room temperature. When applied to autoclaved Chehalis clay loam, purified enzyme lost 75% of its activity after one week and the remainder within two weeks. 相似文献
The objective of the present study is to carry out pharmacokinetic evaluation of oral controlled release formulation (guar gum-based three-layer matrix tablets) containing highly soluble metoprolol tartrate as a model drug. Six healthy volunteers participated in the study, and a two-way crossover design was followed. The plasma concentration of metoprolol tartrate was estimated by reverse-phase HPLC. The pharmacokinetic parameters were calculated from the plasma concentration of metoprolol tartrate versus time data. The delayed T(max) lower C(max) decreased K(a) unaltered bioavailability and prolonged t(1/2) indicated a slow and prolonged release of metoprolol tartrate from guar gum three-layer matrix tablets in comparison with the immediate release tablet dosage form. The results of the study indicated that guar gum three-layer matrix tablets were able to provide oral controlled delivery of highly water-soluble drug such as metoprolol tartrate in humans. 相似文献
