Effect of Pinching and Growth Retardants on Growth and Flowering in African Marigold Cv. Pusa Narangi Gainda

A study on the effect of pinching and application of growth retardants on growth and flowering in African marigold cv. 'Pusa Narangi Gainda' was carried out in the experimental field of Division of Floriculture and Landscaping, Indian Agricultural Research Institute, New Delhi. Treatments comprised pinching, CCC applied at 1000ppm, 1500ppm or 2000ppm, MH at 500ppm, 1500ppm or 2000ppm; B-9 at 500ppm, 750ppm or 1000ppm, and a Control (no pinching). CCC at 2000ppm recorded minimum plant height (46.0cm), maximum plant-spread (56.0cm) and maximum number of branches (19.0), whereas, maximum plant height (67.0cm), minimum plant-spread (29.66cm) and minimum number of branches (5.33) were recorded in Control (non-pinching). As for flowering and yield, application of CCC at 2000ppm recorded maximum flowering-duration (25.33 days), number of flowers per plant (40), single-flower weight (119.46g), flower yield per plant (408.10g), flower yield per unit area (17.83t/ha) and seed yield per plant (17.80 g), Maximum flower diameter (7.93cm) was recorded with application of CCC 2000ppm, whereas, minimum was recorded with pinching (6.2cm). Spray of growth retardants enhanced flower yield compared to that in Control (no pinching). Maximum shelf-life of flower was recorded with CCC 2000ppm (3.66 days), whereas, minimum was recorded with pinching and non-pinching (2.33 days). Thus, application of CCC at 2000ppm is superior to other treatments tested for increasing flower yield in marigold

Evaluation of Anti-Urolithiatic Activity of Malli Chooranam by Ethylene Glycol and Ammonium Chloride Induced Urolithiasis in Male Albino Wistar Rats

In earlier days clinical management of kidney stones requires surgical treatment where as in recent times there are several modern sophisticated methods available for the same which inclusive of percutaneous nephrolithotomy and shockwave lithotripsy. Propensity of reoccurrence is the most common pathetic scenario in both of these invasive procedures which is about 50%. ➢ Researchers are constantly striving hard towards identification of lead for treating urolithiasis either from the synthetic or from herbal origin. Complex formation with ions that tend to promotes crystal growth is the most expected mechanism of the newer therapeutics to become successful against kidney stone. Siddha formulations mainly act by impeding the super saturation of urine and also aids in excretion of excess salt and uric acid thereby it effectively maintains the normal hemostasis and reverse the physiology. ➢ This study concluded that the preliminary phytochemical analysis of aqueous extract of Malli chooranam indicated the presence of alkaloids, flavonoids, phenol, terpenoids. ➢ In vitro antioxidant activity of methanolic extract of Malli chooranam had shown maximum activity at 66.41% at 320 μg/ml. ➢ In vitro calcium oxalate crystallization inhibition by aggregation assay revealed that methanolic extract of Malli chooranam had shown maximum significant inhibition of aggregation in dose dependent manner as that of standard cystone. It exhibited maximum inhibition of 72.35% at 1600μg/ml. ➢ The in-vitro calcium oxalate dissolution study revealed that Malli chooranam has antiurolithiatic activity with a significant maximum dissolution of 68.5% on calcium oxalate crystals. ➢ Animals were divided in to 5 groups. Group I-Control, Group II-Negative control, Group III-treated with standard drug, Group IV-Treated with Lower dose, Group-IV treated with higher dose. Data comparison was made between Group II – Group V. Urolithiasis was induced by feeding ethylene glycol with ammonium chloride for 28 days. ➢ CaOx deposition in the kidneys of EG and ammonium chloride fed by oral route to animals. ➢ Treatment with aqueous extract of Malli chooranam (100 mg/kg, 200 mg/kg) p.o. for 14 days successfully prevented the elevation of deposition of CaOx in kidney when compared to Group II. ➢ Increased urinary excretion of urinary calcium, oxalate, and are observed in EG and ammonium chloride fed animals. Treatment with Malli chooranam (100 mg/kg, 200 mg/kg) for 14 days successfully decreased the excretion of oxalate, calcium when compared to the disease control. ➢ Serum creatinine, uric acid, Urea increased in EG and ammonium chloride fed animals due to decreased GFR. Treatment with Malli chooranam (100 mg/kg, 200 mg/kg) for 14 days successfully decreases the serum creatinine, uric acid, urea when compared to disease control. ➢ The histopathology of kidney was brought to normal in Malli chooranam treated animals when compared to the disease control. ➢ The present study indicates that the administration of aqueous extract of Malli chooranam to rats in ethylene glycol and ammonium chloride induced urolithiasis reduces the growth and development of kidney stones by reducing the stone forming constituents by increasing the GFR. Accordingly, it can be concluded that the supplementation of Malli chooranam has a beneficial effect on urolithiasis. ➢ Further studies are needed to be carried out for determining exact mechanism of action of Malli chooranam for treating urolithiasis

Efficacy of tranexamic acid mouthrinse as a haemostatic agent after extraction in patients who are on anticoagulantand anti platelet therapy

BACKGROUND : Optimal management of patients on anti platelet and anti coagulant who require oral surgery procedure has been controversial. Historically the surgeons have to balance the risk of thromboembolism by reducing or stopping anti platelet and anticoagulant therapy, against the risk of triggering excessive post extraction bleeding if anticoagulation or anti platelet is maintained at therapeutic levels during surgery. Patients on anti platelet and anticoagulants have impaired fibrin formation that is more susceptible to normal fibrinolysis and is believed to be the major cause of post extraction bleeding. In this study the “Efficacy of tranexamic acid mouth rinse as a haemostatic agent after extraction in patients who are on anticoagulant and anti platelet therapy” has been studied. AIMS AND OBJECTIVE: The aim of this study is to verify that this technique is a safe, simple, effective and an acceptable method of patient management. The objective is to identify potential risk factors that may increase the likelihood of bleeding. MATERIALS AND METHODS: One hundred consecutive anti platelet and anti coagulant patients with an International Normalized Ratio (INR) ranges between 1.9 and 3.5 on the day of surgery and who required dental extractions were recruited to this study. Following dental extraction, patients were instructed to use 5 milliliters of 10% tranexamic acid mouth rinse 4 times a day for 7 days, to record bleeding that required pressure to control and their mouth rinse usage. The researcher collected demographic data, details of the state of anti platelet and anticoagulation, details of the surgery and details of bleeding that required additional management. Data entry and analysis were conducted using the statistical computer programme SPSS (16.0). Descriptive statistics were produced for the sample demographics, the pre extraction profile, the post extraction bleeding profile, mouth rinse acceptance and utilization. Identification of potential risks that might increase the likelihood of bleeding was carried out using the paired and unpaired t test appropriate. RESULTS: Of the 100 patients treated, 17 reported bleeding at home on day 1 and 3 patients after day 1. The bleeding reported on these 20 patients was controlled at home only by tranexamic acid pressure pack alone. A further 9 patients reported to the researcher's dental surgery department for bleeding which was then controlled by administering other local haemostatic measures (gelatin foam) with tranexamic acid pressure pack. No patients required hospital admission for systemic management of bleeding. Statistical analysis reveals significant risk factors for post extraction bleeding were as follows: 1. Patients in the age group of 41-60; 2. Pre extraction INR equal to and greater than 2.5 ; 3. Smoking. Factors not statistically significant for an increased risk of bleeding included: 1. The number of teeth removed; 2. Pre-extraction bleeding time and 3. Time on anti platelets and anticoagulants. CONCLUSION : On the basis of research and statistical analysis, it can be concluded that the post-operative use of tranexamic acid mouth rinses in patients who underwent dental extraction at therapeutic INR levels is a safe, simple, effective and an acceptable method of reducing post extraction bleeding

Effect of Plant Growth Regulators on Corm Production in Gladiolus

Experiments (spraying and dipping) were carried out to study the effect of different plant growth regulators with two methods of application on gladiolus cv. Pusa Jyotsna for various parameters of corm production. Spraying TIBA at 500 ppm produced maximum number of corms. Maximum number of cormels was produced by dipping corms in kinetin at 500 ppm concentration. Corm weight was maximum by dipping with 200 ppm of GA3. Spraying GA3 at 500 ppm resulted in maximum weight of cormels per plant and maximum diameter of corms. Dipping in 500 ppm of GA3 produced maximum volume of corms. Propagation co-efficient was maximum in BA at 100 ppm as spray treatment, whereas it was minimum in the case of TIBA at 1500 ppm. This may be due to growth retardation
