Renal arteriovenous malformation presenting with massive hematuria
AbstractRenal arteriovenous malformations are abnormal communications between the intrarenal arterial and venous systems. They are a rare cause of hematuria. Color Doppler ultrasonography, multislice CT angiography, and DSA are important tools for making the diagnosis. We describe the case of a 62-year-old man with renal arteriovenous malformation who presented with gross hematuria
Seasonal fluctuations in birth weight and neonatal limb length; Does prenatal vitamin D influence neonatal size and shape?
Background: Birth weight is known to fluctuate with season of birth, however, there is little information about seasonal variation in neonatal anthropometric measures
Pharmacognostic study of Lepidium sativum Linn (Chandrashura)
Pharmacognosy is the study of naturally occurring biological substances, principally those derived from plants that find use in medicine. The word “Pharmacognosy” is derived from the Greek “Pharmacon,” “a drug” and “gignosco,” to acquire knowledge of. It is closely related to both botany and plant chemistry and both originated from the earlier scientific studies on medicinal plant. The plant kingdom still holds many species of plants containing substances of medicinal value which have yet to be discovered large number of plants constantly being screened for their possible pharmacological value. The plant Chandrashura is being used for the treatment of Amavata, Sandhivata, and Katishula successfully. Here, an attempt is made to study the plant pharmacognostically; the part taken for study is the seed. Diagnostic features of seed and seed powder were also worked out and the details were presented
Study on removal of <i>m</i>-phenylenediamine from aqueous solution by adsorption over granular activated carbon
42-47m-Phenylenediamine (MPD) is used for manufacture of thin film
composite reverse osmosis (RO) membrane in polyamide thin film formation by
interfacial polymerization. The used m- phenylenediamine solution has to
be discarded as effluent. Granular activated carbon is found to be an efficient
adsorbent for removal of m-phenylenediamine from aqueous solution.
Brunauer-Emmett-Teller (BET) surface area of the granular activated carbon is
446 m2/g and micropore volume 0.15 cc/g. A systematic study of
adsorption of m-phenylenediamine over granular activated carbon with
different loading of adsorbent in given m-phenylenediamine solution
concentration and different concentration of m-phenylenediamine solution
in given adsorbent quantity has been carried out. Adsorption isotherms have
been developed in each case. It is found that at 28% w/v concentration of
adsorbent, the total MPD present in the 2% aqueous solution is adsorbed. It is
found that adsorption of MPD over granular activated carbon follows Freundlich
isotherm x/m = k c1/n , where k =0.4576 and n = 4. Moreover, the
study involves kinetics of adsorption of m-phenylene diamine over
granular activated carbon at different temperatures and it is found that the
kinetics of MPD adsorption over granular activated carbon follows Elovich
Model. The kinetic study indicates that the optimum temperature of
adsorption is 40<span style="font-family:Symbol;mso-ascii-font-family:

Significance of Peripheral Blood Smear in Diagnosis of Blood Parasitic Infection
Bancroftian filariasis is a tropical and subtropical disease caused by Wuchereria bancrofti and transmitted by the Culex mosquitoes. It is conventionally diagnosed made by demonstrating microfilariae in the peripheral blood smear. Microfilariae and adult filarial worm have been incidentally detected in the blood. We here report an unusual case of Bancroftian microfilariasis in a 28-year-old male coming from endemic area with history of fever since 1 month. Patient had history of yellowish discoloration of skin and sclera

A comparative study on different market samples and standard samples of Shalaparni through physicochemical methods and near infrared spectroscopy
Dashmoolais one of the most important groups explained in Mishrakagana. One of which, Shalaparni is a potent drug used single as well as in various formulations mentioned in classics. Adulteration in Dashmoolaplants is a very big issue now days and this is because of the lack of availability of the original drugs. In this study market samples of Shalaparni (Desmodium gangeticum DC.) collected from the different part of India; compared with the standard Shalaparni authenticated sample which was collected from the natural source; by using physicochemical parameter and near infrared spectroscopy. Results were statistically processed by PCA. The results show that there is no similarity found outbetween the standard drug and market samples of Shalaparni which were collected from different regions of India. The market samples were observed for different adulterated material having poor quality
