1.  Effect of Drakshavaleha in cyclophosphamide induced weight loss and reduction in crown-rump length in developing mice embryo 
Ayu  2013;34(2):215-219.
Being an anti-mitotic and apoptosis inducing agent, Cyclophosphamide (CP) causes stunting in size and loss of body weight of the pups on intra-peritoneal injection (10 mg/kg) to pregnant mice on day 11 of gestation. Loss of body weight due to CP administration could be minimized by feeding Drakshavaleha (16 g/kg) orally to pregnant mice from day “0” to day “18” of their gestation. Recovery observed in terms of body weight of the pups was statistically significant (P < 0.001) in Drakshavaleha treated pups. Drakshavaleha also recovered the crown-rump length of the pups occurred due to CP administration. Growth retardation with decreased fetal weight was observed in all CP treated pups when compared with the controls.

2.  Pharmaceutical study of Lauha Bhasma 
Ayu  2010;31(3):387-390.
In the present research paper, the work done on pharmaceutical study of Lauha Bhasma conducted in the Department of Rasa Shastra under the postgraduate research programme is being presented. The pharmaceutical processing of Lauha Bhasma was performed by following samanya shodhana, vishesha shodhana and marana of Lauha. Under the process of marana, three specific pharmaceutical techniques were followed, viz. bhanupaka, sthalipaka and putapaka. During the putapaka process, an electric muffle furnace (EMF) was used. The temperature of puta was studied in two batches, viz. in Batch I, a temperature of 800°C was maintained whereas in Batch II, a temperature of 600°C was maintained. The purpose behind selecting two temperatures was to validate the process of marana of Lauha and to determine an ideal temperature for the preparation of Lauha Bhasma in EMF. It is found that after 20 puta at a temperature of 600°C, the Lauha Bhasma was prepared properly. The entire characteristic of Lauha Bhasma, like “pakwa jambu phala varna,” varitar, etc. was attained at 600°. At a temperature of 800°C, the process could not be carried out smoothly. The pellets turned very hard and brassy yellow in color. The desired color was attained only after decreasing the temperature in further puta.
