ABSTRACT
BACKGROUND: Tennis elbow is a common musculoskeletal disease of elbow and causes restricted movement of forearm. Various treatment modalities like NSAID, corticosteroid injection, counter bracing, physiotherapy, surgery etc are available but safety and efficacy of one treatment over another is under research. Ayurveda classifies this condition as Snayugata vata. According to Sushruta, Agnikarma (thermal cautery) is the one among the treatment modalities for Snayugata vata. Previously published randomised controlled trials have shown that therapeutic ultrasound is safe and effective for tennis elbow. However, the comparative efficacy of these two treatment modalities is unknown. OBJECTIVE: This study compares the effects of Agnikarma (AGK) with Therapeutic Ultrasound (TUS) in reducing pain, tenderness and restores the ability to do various tasks. MATERIALS AND METHODS: A total of 30 patients were enrolled in the study as an open-label, double-armed, prospectively designed comparative clinical study, with 15 patients in each group. Group AGK received two sittings of Agnikarma and Group TUS received therapeutic ultrasound. To analyze the patients, three outcome measures were adopted: pain intensity, assessed with a Numerical Pain Rating Scale, tenderness - Grade 0 to Grade 4 (mentioned in Hutchinson's clinical methods) and pain and functional Disability assessed with the Patient Rated Tennis Elbow Evaluation (PRTEE) questionnaire. Assessment was done on 0th, 8th, 15th, 30th and 60th day. RESULT: Tennis elbow can be effectively treated with AGK and TUS. (p < 0.001 for pain, tenderness and PRTEE). While comparing between the groups, on 8th day and 15th day statistically significant difference in pain and PRTEE (p < 0.05) was noted between AGK and TUS groups. Agnikarma showed better results than therapeutic ultrasound in pain management and showed an improved quality of life from 8th day onwards and for a period up to 2 months. CONCLUSION: Both Agnikarma and therapeutic ultrasound have roles in the management of tennis elbow. However, starting on the 8th day and continuing for up to 2 months, Agnikarma showed a significant benefit in pain management and improved status for quality of life.
ABSTRACT
The effective reversion of hyperhydricity (HH) in Dianthus chinensis L. facilitated efficient in vitro production of hyperhydricity-free plantlets. Under routine sub-culture practice, the problem of HH arises after third sub-culture in agar (0.85%) gelled Murashige and Skoog (MS) medium containing 2.5 µM 6-benzyladenine (BA). To confirm the role of ethylene on hyperhydricity induction, an ethylene releasing compound ethephon (5 µM) was used in combination with 2.5 µM BA and demonstrated 100% HH with reduced stomatal aperture. Supplementation of 10 µM silver nitrate (AgNO3) to 2.5 µM BA containing medium resulted HH reversion with reduced shoot number (19.0); however, addition of 5 µM cobalt chloride (CoCl2) produced highest microshoots (202.0). The combination effect of AgNO3 (10 µM), CoCl2 (5 µM), and BA (2.5 µM) showed complete HH reversion and upheld normal microshoots (55.0) with reduced relative water content (78.3%). The Ag and Co salts regulate ethylene biosynthesis and thereby 50% reductions in H2O2 content characterized by formation of green healthy shoots with proper stomatal morphology. The gene expression profile of 1-Amminocyclopropane-1-carboxylase synthase (ACS1) and 1-Amminocyclopropane-1-carboxylic acid oxidase (ACO1) showed reduced expression after the retroversion of microshoots in anti-ethylene reversion medium compared to hyperhydric shoot. In vitro raised shoots were rooted (93.3%) ex vitro by 10 mM IBA treatment and 92.2% plants were survived. The genetic stability of micropropagated plants were analyzed and proved that addition of low levels of heavy metal salt in the medium does not cause any variation in banding pattern. The protocol forwards a novel method to revert HH of in vitro cultures by adopting intermittent exposure of anti-ethylene compounds added in the medium and the procedure can be applied to many other plants facing similar HH problems.

ABSTRACT
Hyperhydricity (HH) is a physiological disorder that frequently occurs in plant tissue cultures, affecting healthy growth and development of clonal plants. The primary cultures raised in Murashige and Skoog (MS) medium supplemented with 2.5 µM N6-benzyladenine (BA) produced normal microshoot (6.3 shoots/ culture) with least HH. However, the third subculture onwards, HH becomes a major problem. The role of ethylene on HH induction through stomatal closure mechanism were proved by the supplementation of ethephon (5 µM) in the culture medium containing 2.5 µM BA. In the present study, the application of polyamines (putrescine, spermidine, or spermine) to minimize the HH was examined. Supplementation of 5 µM spermine in MS medium significantly reduced the percentage of HH to 0.33%, in contrast to control (100%), while a maximum number of healthy reverted shoots (11.0) were observed in 5 µM spermidine treatment. The addition of polyamines effectively reduced H2O2 content (50%) characterized by increased chlorophyll content with proper stomatal morphology. The relative gene expression profile of ethylene biosynthesis genes, 1-Aminocyclopropane-1-carboxylase synthase (ACS1) and 1-Aminocyclopropane-1-carboxylic acid oxidase (ACO1) at 5 µM spermine added medium was 1.09 and 1.3 over normal (1) or HH cultures (1.93 and 2.53) respectively, and thus directed restoration of normal morphology of shoots. The present finding in brief, forward a novel method to regulate HH in terms of endogenous ethylene by adopting polyamines exposure and the procedure can be applied to many other plants facing similar HH problems.
ABSTRACT
Pyrogens are heterogeneous group of fever-inducing substances derived from Gram-positive and Gram-negative bacteria, fungi, and viruses. They incite immune response by producing endogenous pyrogens such as prostaglandins and other proinflammatory cytokines like IL-1ß, IL-6, and TNF-α. The present study was to analyze the influence of cryopreservation in IL-1ß release, a marker for inflammatory response from human lymphocytes, in response to exogenous pyrogenic stimulants. Lymphocytes isolated from pooled blood of multiple healthy individuals were cryopreserved in DMSO and glycerol for periods of 7, 14, 30, and 60 days and were challenged with LPS and LTA in vitro. The inflammatory cytokine, IL-1ß release, was measured by ELISA method. It was observed that the release of IL-1ß increases instantaneously after the initiation of incubation and reaches a maximum at 3 to 5 hours and then gradually decreases and gets stabilized for both pyrogens. Moreover it was also observed that the effect of cryoprotectants, DMSO (10%) and glycerol (10%), showed almost similar results for short-term storage, but DMSO-preserved lymphocytes yielded a better viability for long-term storage. Thus, the isolated cryopreserved lymphocytes system can be a promising approach for the total replacement/alteration to animal experimentation for pyrogenicity evaluation.
