We present a case of necrotizing pneumonia in an 87-year-old man without severe respiratory instability. Clinical suspicion arose due to the need for supplementary oxygen and persistent fever during treatment for community-acquired pneumonia. The diagnosis was confirmed by chest computed tomography. Although necrotizing pneumonia typically requires major surgical intervention upon diagnosis, we chose conservative management with antimicrobials and chest drainage alone. The patient experienced significant improvement and resolution of pneumonia with conservative management.

The current work imitates the trivial method which intricates the abstraction along with classification of caffeine accessible in variability of decoction shrubberies which are expended in two different states of India (Telengana & Uttar Pradesh). As per observation individuals of both the states are identical tender of consumption of tea. Abstraction progression tangled variability of stages which are discoursed in the work. In addition, the outcome of drinking of caffeine or the permitted ingestion of caffeine over tea has also been conferred through the work and linked the data with the literature data. In this study, we used a UV-visible spectrophotometer as well as liquid-liquid extraction method to determine the caffeine content in various tea samples. The significance of this study lies in the fact that accurate determination of caffeine content is essential for quality control and labeling of tea products. The UV-visible spectrophotometer method was found to be simple, reliable, and sensitive for the detection of caffeine in tea samples.

Objective: To test the effects of dietary supplementation of Lepidium sativum (LS) seed powder on growth performance and gonadotropins secretion in ovariectomized, estradiol-implanted rabbits. Methods: Ovariectomized, estradiol-implanted Chinchilla rabbits were assigned into four experimental groups: LS seed powder was included into normal rabbit chow at 0% (control), 5% (low), 7% (mid) and 10% (high) w/w. Experimental feed and water were given ad-libitum for 3 weeks. Weekly body weights and daily feed intake of rabbits were recorded. Twenty-one days post-feeding, blood samples were collected at 15-minute interval for 3 h (PeriodⅠ) after which 2.5 μg gonadotropin-releasing hormone (GnRH) was injected intravenously and the sampling continued for another hour (PeriodⅡ). Plasma was harvested and analyzed for luteinizing hormone (LH) and follicle-stimulating hormone (FSH) by radioimmunoassay. Results: Feed intake was significantly (P<0.05) increased in LS-supplemented rabbits. However, the increase in feed intake did not result in significant body weight gain. LS seed supplementation significantly (P<0.001) increased mean plasma LH dose-dependently from the low- to the mid-LS level and then decreased LH at the high-LS level. LS supplementation increased (P<0.001) plasma FSH secretion. Injection of GnRH had no effect on plasma LH, however significantly (P<0.05) decreased overall plasma FSH secretion. Conclusions: LS seed supplementation stimulates feed intake and gonadotropins secretion in rabbits. Gonadotropins effect may be mediated through LS seeds phytosterols through the activation of estrogen receptors thereby producing agonistic effects resulting in LH and FSH secretion. The differential responses of gonadotropins to GnRH in LS-supplemented rabbits suggest differential regulation of the synthesis and secretion of these gonadotropins.
