This document discusses substitution of herbal drugs in Ayurveda. It begins by noting that 195 medicinal plant species are red listed due to threats to their populations. Substitution is generally done when the original material is unavailable or in insufficient quantity, and the substitute should have similar therapeutic effects. Criteria for substitution include similarity in taste, qualities, and pharmacological effects. Validation of a substitute involves confirming these properties as well as its effects in formulations. Cultivated varieties and locally available alternative species are suggested as potential substitutes. The document examines specific examples of substitution and evaluates them based on chemical and effect profiles.

Vipaka comes under the five concepts under the study of a dravya (Rasapanchakas). In Ayurveda the digestion & metabolism of any substance is explained in two stages:
Avasthapaka
Nishtapaka
Avasthapaka is the first phase considered as digestion.
In charaka the word “prapaka” is used as the synonym for avasthapaka.
Nishtapka or Vipaka is the second phase and considered as metabolism.

Evaluation of in vitro antibacterial activity of Caralluma lasiantha for scie...Ratnakaram Venkata Nadh
Caralluma lasiantha is used as a traditional medicine in India to heal body
heat and inflammations. In order to find out a scientific validation for the Indian
traditional knowledge, antibacterial activity of C. lasiantha extracts was studied
against inflammation causing bacteria (viz., Staphylococcus aureus, Escherichia coli,
Streptococcus Sp., Bacillus subtilis, Enterobacter aerogenes, Klebsiella pneumoniae)
along with other Gram-positive and Gram-negative bacteria. Solvents with different
polarity were used for extraction from dry roots and stems. Minimum inhibitory
concentrations (MIC) were also studied. Differential antibacterial activity was
exhibited by extracts and higher inhibition potential against Gram-positive bacteria
was explained. The observed antibacterial activities were correlated with the chemical
structures of phytochemicals present in C. lasiantha. Anti-inflammation activities
are related to C. lasiantha extracts through their antibacterial activities.
A large percentage of plants used in Ayurvedic practices and herbal medicines are subjected to controversy. Controversial drugs or Sandigdha Dravyas is term used for medicinal plants having controversial botanical sources due to polynomial nomenclature system of Sanskrit, non availability of plants and parallel evolved knowledge.
Adulterants and Substitutes are the common practices in herbal raw material trade. Adulteration is a debasement of article intentionally for commercial purpose or accidentally due to lack of knowledge of identification and proper collection.
Substitution is a replacement of equivalent drugs in place of original drugs on the basis of similar Rasa, Guna, Veerya, Vipak and mostly on Karma.

Zizyphus rugosa Lam. (Family: Rhamnaceae), locally known as “Bon Boroi” or as “Jongli Boroi” in Bangladesh generally found as a herb on the hills in bunches on thorny branches of the Zizyphus rugosa trees. Its bark and wood are used medicinally for dysentery in China, India, Laos, Burma, Sri Lanka, Thailand and Vietnam. Phytochemical screening of the Leaf extract of Zizyphus rugosa Lam showed different phytoconstituents including carbohydrates (monosaccharides, reducing and mixed-reducing sugars), alkaloid, glycosides, steroids, tannins and saponin. No flavonoid was detected. In DPPH and NO radical scavenging methods, IC50 was moderately satisfactory. IC50 was found 179.713μg/ml and 769.909μg/ml respectively compare with the reference ascorbic acid (15.707μg/ml and 82.642μg/ml respectively). In LPO (Lipid peroxidation) assay the Leaf fraction extract showed moderate inhibition potentiality (IC50 402.835μg/ml) in comparison to standard drug BHT (IC50 32.94μg/ml). In CUPRAC assays, the fraction was found to possess low Total antioxidant content, good flavonoid, and moderate amounts of phenolics, tannin and alkaloid content. The Leaf fraction extract was found to show good toxicity to Brine Shrimp nauplii, (LC50 212.402μg/ml & LC90 10715.91μg/ml) compare with the reference anticancer drug vincristine sulphate (LC50 2.47μg/ml & LC90 42μg/ml). In the antimicrobial study the fraction showed moderate activity against only one bacterium (Shiggla sonni) while the standard drug Chloramphenicol showed very good zone of inhibition against all five types (Salmonella typhi, Staphylococcus aureus, Shiggla sonni, Salmonella paratyphi, Salmonella grb) of bacteria. These findings provide scientific basis for the use of Zizyphus rugosa Lam. leaf ethanolic extract in traditional medicine in the treatment of aforementioned diseases. The plant also possesses moderate antimicrobial activity, good cytotoxic and good to moderate antioxidant activity.
A Preliminary Study on Phytochemical Screening of Boerhaavia Diffusa, Euphorb...ijtsrd
Medicinal plants are of great importance to the health of individuals and communities. The medicinal value of these plants lies in some chemical substances that produce a definite physiological action on the human body. The objective of the present study was to evaluate the phytochemical constitution and antioxidant activity of Aqueous extracts of three selected plant Boerhaavia diffusa, Euphorbia hirta and Amaranthus polygonoides. Preliminary phytochemical screening revealed the presence of phytochemicals like alkaloids, flavonoids, Steroids, phenols, tannin and carbohydrates in Boerhaavia diffusa and Euphorbia hirta where as in Amaranthus polygon ides many phytoconstituents like alkaloids, flavonoids, Steroids, terpenoids, phenols, saponin, tannin and carbohydrates were present. Antioxidants are the compounds which terminate the attack of reactive species and reduce the risk of diseases. The free radicals oxidants are species with very short half life, high reactivity and damaging activity towards macromolecules like proteins, DNA and lipids. The results of antioxidant activity of three aqueous extract showed maximum activity in different concentration of 50, 250, 500, 750 and 1000 µg ml. The percent inhibition of aqueous extract of Boerhavia diffusa , Euphorbia hirta , Amaranthus polygonoides was 176.15, 404.78 and 413.06 respectively. In the present work potent anti oxidant activity of aqueous extract of Boerhaavia diffusa was higher when compared to other two extracts. The present study revealed that the plant extract possessed good antioxidant activity and less quantity of toxic metals, which therefore can be used as a natural source of free radical scavenger. However, further study needs to be carried out to know its mode of action. R. Ezhilarasi | Dr. B. Senthilkumar | Dr. K.

New Directions in Targeted Therapeutic Approaches for Older Adults With Mantl...i3 Health
i3 Health is pleased to make the speaker slides from this activity available for use as a non-accredited self-study or teaching resource.
This slide deck presented by Dr. Kami Maddocks, Professor-Clinical in the Division of Hematology and
Associate Division Director for Ambulatory Operations
The Ohio State University Comprehensive Cancer Center, will provide insight into new directions in targeted therapeutic approaches for older adults with mantle cell lymphoma.
STATEMENT OF NEED
Mantle cell lymphoma (MCL) is a rare, aggressive B-cell non-Hodgkin lymphoma (NHL) accounting for 5% to 7% of all lymphomas. Its prognosis ranges from indolent disease that does not require treatment for years to very aggressive disease, which is associated with poor survival (Silkenstedt et al, 2021). Typically, MCL is diagnosed at advanced stage and in older patients who cannot tolerate intensive therapy (NCCN, 2022). Although recent advances have slightly increased remission rates, recurrence and relapse remain very common, leading to a median overall survival between 3 and 6 years (LLS, 2021). Though there are several effective options, progress is still needed towards establishing an accepted frontline approach for MCL (Castellino et al, 2022). Treatment selection and management of MCL are complicated by the heterogeneity of prognosis, advanced age and comorbidities of patients, and lack of an established standard approach for treatment, making it vital that clinicians be familiar with the latest research and advances in this area. In this activity chaired by Michael Wang, MD, Professor in the Department of Lymphoma & Myeloma at MD Anderson Cancer Center, expert faculty will discuss prognostic factors informing treatment, the promising results of recent trials in new therapeutic approaches, and the implications of treatment resistance in therapeutic selection for MCL.
Target Audience
Hematology/oncology fellows, attending faculty, and other health care professionals involved in the treatment of patients with mantle cell lymphoma (MCL).
Learning Objectives
1.) Identify clinical and biological prognostic factors that can guide treatment decision making for older adults with MCL
2.) Evaluate emerging data on targeted therapeutic approaches for treatment-naive and relapsed/refractory MCL and their applicability to older adults
3.) Assess mechanisms of resistance to targeted therapies for MCL and their implications for treatment selection

The prostate is an exocrine gland of the male mammalian reproductive system
It is a walnut-sized gland that forms part of the male reproductive system and is located in front of the rectum and just below the urinary bladder
Function is to store and secrete a clear, slightly alkaline fluid that constitutes 10-30% of the volume of the seminal fluid that along with the spermatozoa, constitutes semen
A healthy human prostate measures (4cm-vertical, by 3cm-horizontal, 2cm ant-post ).
It surrounds the urethra just below the urinary bladder. It has anterior, median, posterior and two lateral lobes
It’s work is regulated by androgens which are responsible for male sex characteristics
