The stomach plays an important role in the digestion of the things we consume. This part of the body can withstand a wide range of harmful substances, such as hydrochloric acid, alcohol, refluxed bile salts, and other irritants. Upper abdominal pain may be a symptom of a gastrointestinal disorder known as Peptic Ulcer if you eat an unhealthy diet, smoke, drink too much alcohol, or take NSAIDs on a regular basis. You may also have a sedentary lifestyle. Today, gastric hyperacidity and gastroduodenal ulcers are very common problems all over the world. In this article, the author tries to give an overview of the in vivo and in vitro screening models that have been used in different laboratories and their validation during the past few decades to carry out such investigations, along with the underlying mechanisms of ulcer induction in each approach. The goal is to educate of the various experimental models available for conducting novel investigations to gain further knowledge in context to peptic ulcers.
胃在消化我们摄入的食物方面起着重要的作用。这部分身体可以承受各种有害物质,如盐酸、酒精、反流胆汁盐和其他刺激物。如果你饮食不健康、吸烟、酗酒或经常服用非甾体抗炎药,上腹部疼痛可能是消化性溃疡这一胃肠道疾病的症状。你也可能有久坐不动的生活方式。今天,胃酸过多和胃十二指肠溃疡是世界上非常常见的问题。在这篇文章中,作者试图给出体内和体外筛选模型的概述,这些模型已经在不同的实验室中使用,并且在过去的几十年里进行了这些研究,以及每种方法中溃疡诱导的潜在机制。目的是教育各种实验模型可用于开展新的调查,以获得消化性溃疡背景下的进一步知识。

The quality control of herbal medicines has become a major concern to health authorities, health care providers and the manufacturing industries at every stage of production. The standardization of raw drugs and formulations with the help of modern analytical tools increase their scope, acceptance and scientific validity. The safety and efficacy of herbal medicines largely depend on their quality. Neelibhringadi keratailam is an excellent hair growth promoting oil widely prescribed and marketed in Kerala. All the ingredients in the formulation are best hair growth promoters. The knowledge of hair products, their mode of action, efficacy and ingredients has become more relevant today. Neelibhringadi keratailam manufactured by GMP certified Ayurvedic companies in Kerala was assessed by evaluating and comparing the physico chemical parameters of market samples of Neelibhringadi keratailam with that of prepared Neelibhringadi keratailam. Physico chemical parameters such as Acid value (AV), Iodine value (IV), Refractive index (RI) Saponification value (SV), Specific gravity (SG), Weight per milliliter, HPTLC, ICP-MS and microbial contamination of market samples were evaluated and compared with those of prepared sample. Neelibhringadi keram was prepared and its physicochemical analysis was done and compared with market samples. Analysis of the market samples showed significant variation in physicochemical analytical parameters, colour and consistency from the prepared samples.
草药的质量控制已成为卫生当局、卫生保健提供者和制造业在生产的每个阶段关注的主要问题。在现代分析工具的帮助下,原料药和配方的标准化增加了它们的范围、接受度和科学有效性。草药的安全性和有效性在很大程度上取决于它们的质量。Neelibhringadi keratailam是一种极好的促进头发生长的油,在喀拉拉邦广泛开处方和销售。配方中的所有成分都是最好的头发生长促进剂。护发产品的知识,它们的作用方式,功效和成分已经变得更加相关的今天。由喀拉拉邦GMP认证的阿育吠陀公司生产的Neelibhringadi keratailam通过评估和比较Neelibhringadi keratailam的市场样品和制备的Neelibhringadi keratailam的物理化学参数来进行评估。对市售样品的酸值(AV)、碘值(IV)、折射率(RI)、皂化值(SV)、比重(SG)、每毫升重量、HPTLC、ICP-MS、微生物污染等理化参数进行评价,并与制备样品进行比较。制备了尼利布林加迪香膏,对其进行了理化分析,并与市售样品进行了比较。对市场样品的分析显示,与制备样品相比,理化分析参数、颜色和稠度有显著差异。

Activation of the oncogenes and inhibition of the apoptotic function of the p53 protein is a gateway for the cancer genesis. Interaction of the MDM2 protein with p53 protein is responsible for the inhibition of the p53 function. Inhibiting the p53-MDM2 interaction by drug will lead to the p53 release in the cancer cells. And can restart the apoptosis in the cancer cell. Computational methods successfully used for the design and development of the new, potent MDM2 inhibitors. Researchers and pharma companies used rational approach like target-based drug design or ligand-based drug design to develop the novel MDM2 inhibitors. The number of MDM2 inhibitors, has been designed by the computer-aided drug design and in-silico studies. In clinical studies, MDM2 inhibitors are led by RG7112. RG7112 completed its phase-1 trials in 2016, and recently it is under phase-2 trials. Along with RG7112, the number of potent MDM2 inhibitors entered the clinical trials successfully. It indicates the successful development of this class (MDM2 inhibitors). MDM2 inhibitors were found very effective in various studies for the treatment of various kinds of cancers. They have good selectivity for the tumor cells over the normal cells. It induced the dose dependent cell cycle arrest only; in the normal cells. In studies, MDM2 inhibitors successfully detached the p53 protein from the MDM2 protein. And restart the cell-killing function of the p53 protein in the cancer cells. Hence, MDM2 inhibitors can selectively kill the cancer cells over the normal cells.
癌基因的激活和p53蛋白凋亡功能的抑制是癌症发生的门户。MDM2蛋白与p53蛋白的相互作用是抑制p53功能的原因。通过药物抑制p53- mdm2相互作用可导致p53在癌细胞内释放。并能重启癌细胞的凋亡。计算方法成功地用于设计和开发新的,有效的MDM2抑制剂。研究人员和制药公司采用基于靶标的药物设计或基于配体的药物设计等合理方法开发新型MDM2抑制剂。MDM2抑制剂的数量,已经通过计算机辅助药物设计和计算机研究进行了设计。在临床研究中,MDM2抑制剂以RG7112为先导。RG7112于2016年完成了第一阶段试验,最近正在进行第二阶段试验。与RG7112一起,许多强效MDM2抑制剂成功进入临床试验。这表明这类(MDM2抑制剂)的开发成功。在各种研究中发现MDM2抑制剂对治疗各种癌症非常有效。与正常细胞相比,它们对肿瘤细胞有很好的选择性。仅诱导剂量依赖性细胞周期阻滞;在正常细胞中。在研究中,MDM2抑制剂成功地将p53蛋白从MDM2蛋白中分离出来。重新启动癌细胞中p53蛋白的细胞杀伤功能。因此,MDM2抑制剂可以选择性地杀死癌细胞而不是正常细胞。

PRACTICAL UTILITY OF SAMSARJANA KRAMA: A REVIEW 轮回羯摩的实际效用:述评
Pub Date : 2021-10-14 DOI: 10.7897/2230-8407.1210167

The Shodhana procedures are mainly divided into three phases known as Trividha Karma. Acharya Dalhana has clarified Trividha Karma in the context of Shodhana as Poorva Karma, Pradhana Karma and Paschat Karma. Samsarjana Krama is a special diet pattern which is followed as Paschat Karma after Samshodhana. After Samshodhana Karma the Atura Shareera will have reduced tolerance owing to the elimination of large quantities of Dosha and Mala from the body, leading to weakness and reduction in digestive fire. This can be corrected only by following proper Samsarjana Krama with respect to the Shuddhi attained by the Atura. Acharyas detailed the Samsarjana Krama for two Annakala with respect to the ancient time period in contrast to the present scenario, where we are following three Annakala. To get a successful result from the treatment the patient should follow all the 3 stages properly. Hence, here an attempt is made to modify the Samsarjana Krama chart for the present era with respect to classical information given by the Acharyas.
修持过程主要分为三个阶段,称为三业。《阿查里亚·达尔哈那》阐明了三生业在贫乏业、Pradhana业和Paschat业的背景下的因果关系。轮回之羯磨是一种特殊的饮食模式,在轮回之羯磨之后,作为Paschat Karma遵循。在三观业力之后,由于从身体中消除了大量的多沙和玛拉,导致虚弱和消化火的减少,阿图拉的容忍度会降低。这只能通过遵循正确的轮回戒律来纠正,以达到阿图拉所达到的首地。阿查里亚详尽地描述了古代时期两个安娜卡罗的轮回,而不是我们现在跟随三个安娜卡罗的情景。为了从治疗中获得成功的结果,患者应该正确地遵循所有三个阶段。因此,本文试图根据阿查里亚所提供的经典信息,为当前时代修改《轮回克拉玛图》。

Orodispersible tablets (ODTs) are novel drug delivery systems that have the potential to significantly affect conventional dosage forms in terms of patient compliance, convenience, bioavailability, and time to action. Despite the fact that significant research has gone into developing ODT formulations and technologies, in order to produce newer, more expense technologies and better items, more research is needed in these major destinations. Because of the availability of new technologies, as well as good market acceptance and patient compliance, the potential of dosage forms is attractive. Pharmaceutical companies can use ODTs for new product lines or first-to-market products, which is a factor in technology. With the continuing development of new pharmaceutical excipients, more unique ODT technologies are likely to occur soon. Method -For the orodispersible tablet optimized formulation, a direct compression method was used. Result: The pure dosage calibration curve was created by dissolving the medication in ethanol and measuring the absorbance with a UV spectrophotometer set at 243.5 nm.

Ayurveda (Science of life) has explained about the pathogenesis and the treatment of various disorders, the incidence of some of which have increased in the present scenario due to altered diet habits and lifestyle. Janu Sandhigata Vata is one among the Vata Vyadhi which causes a lot of inconvenience and disability in day-to-day activities. It is compared to Osteoarthritis of knee in modern Science. In this case study, a female aged about 57 years presented in the OPD of SSCASRH, Bengaluru was diagnosed with Janu Sandhigata Vata of both the knee joints. Arohana Krama Matra Basti with Prasarini taila was planned as per Sharangadhara’s reference. There was significant improvement in the patient and was evaluated after treatment and also during follow up. There was marked relief with respect to her subjective complaints like pain, improved joint space, walking time, degree of flexion and extension & X ray. This type of Arohana Krama Matra Basti can be adopted in future for planning treatment in Janu Sandhigata Vata and also taken up in a larger group study to check for better relief, long term effect and reduced side effects. The case is further elaborated in the article
阿育吠陀(生命科学)已经解释了各种疾病的发病机制和治疗方法,其中一些疾病的发病率由于饮食习惯和生活方式的改变而在目前的情况下有所增加。Janu Sandhigata Vata是Vata Vyadhi中的一个,在日常活动中造成很多不便和残疾。现代科学将其与膝关节骨关节炎相比较。在本病例研究中,一名年龄约57岁的女性在班加罗尔SSCASRH的门诊就诊,被诊断为双膝关节Janu Sandhigata Vata。Arohana Krama Matra Basti和Prasarini taila是按照Sharangadhara的参考计划的。在治疗后和随访期间,患者有了显著的改善。她的主诉如疼痛、关节空间改善、行走时间、屈伸程度和X光片均有明显缓解。这种类型的Arohana Krama Matra Basti可以在未来的Janu Sandhigata Vata计划治疗中采用,也可以在更大的群体研究中采用,以检查是否有更好的缓解,长期效果和减少副作用。文章对该案例进行了进一步的阐述

The application of the ratio spectra derivative spectrophotometry to the simultaneous determination of Paracetamol (PCM) and Tapentadol (TAP) in combined pharmaceutical tablets is presented. The spectrophotometric procedure is based on the use of the first derivative of the ratio spectra obtained by dividing the absorption spectrum of the binary mixtures by a standard spectrum of one of the compounds. The first derivative amplitudes were measured at 220 and 232 nm for the assay of TAP and PCM, respectively. Calibration graphs were established for 1-5 μg mL-1 for TAP and 6.5-32.5 μg mL-1 for PCM in binary mixture. The detection limits for TAP and PCM were found 0.098 and 0.595 μg mL-1, respectively, while the quantification limits were 0.298 μg mL-1 for TAP and 1.805 μg/ml for PCM. The relative standard deviations were found to be less than 2%, indicating reasonable repeatability of both methods. The proposed methods were hence validated as per ICH guidelines and successfully applied to the determination of these drugs in commercial tablets.
建立了比值光谱导数分光光度法同时测定复方片剂中扑热息痛(PCM)和他他他多(TAP)含量的方法。分光光度法的方法是基于用二元混合物的吸收光谱除以其中一种化合物的标准光谱得到的比值光谱的一阶导数。TAP和PCM的一阶导数振幅分别在220和232 nm处测定。建立二元混合物中TAP浓度为1 ~ 5 μg mL-1、PCM浓度为6.5 ~ 32.5 μg mL-1的标定图。TAP和PCM的检出限分别为0.098和0.595 μg ml -1, TAP和PCM的定量限分别为0.298和1.805 μg/ml。两种方法的相对标准偏差均小于2%,重复性良好。因此,所提出的方法根据ICH指南进行了验证,并成功地应用于商业片剂中这些药物的测定。
