The effect of feeding the silkworm Bombyx mori L. on six different mulberry variety Morus alba var. Kokuso-27, Sh2 x Lunlog, Kaeryang-ppong, Kanava-2, Leavigata, and Morus nigra var. Arandaly on some enzymatic activities which affect silk production was studied 3-Phosphoglycerate Dehydrogenase (3-PGD, Glutamic Oxaloacetic Transaminase (GOT) and Glutamate Pyruvic Transaminase (GPT) which play a vital role in the synthesis of silk protein were determined.Results indicated that feeding silkworm larvae on Morus alba var. Kokuso-27 represented the highest rate of 3-PGD activity (6.14 u/mg) followed by Sh 2 xLunlog variety (5.76 u/mg) and Arandaly (4.2 u/mg) while, slight differences in 3-PGD activity was found between the other three varieties. The same with GPT enzyme, the mulberry varieties Morus alba var Kokuso-27 followed by Sh 2 xLunlong fed to larvae resulted in a high rate (5.

The study examines the validity of five biochemical parameters as indicators for the activity and intensity of asthma induced by the house-dust mite allergy. Blood samples of forty children (28 males and 12 females of 0.5-15 years old) suffering from moderate (31) and severe (9) attack of asthma and of 10 non asthmatic children (6 males and 4 females of similar age range) were examined. Levels of histamine, total serum IgE, SIgE, ECP and AEC were significantly higher in the asthmatic-than in the normal cases. Furthermore, severe asthmatic cases had significantly higher levels as compared to the moderate ones, i.e., mean values for [Moderate < Severe] > Check cases. As a conclusion, the elevated levels of such biochemical parameters are associated with HDM asthmatics and are correlated with the severity of asthma attacks. Thus these five parameters may be considered as good markers for HDM asthma activity and severity.
