Objective: To probe into the target organ of Fenglong (ST 40) and the mechanism in resolving phlegm.
Methods: Thirty SD rats were randomly divided into 3 groups, a blank control group, a model group and a Fenglong group, 10 rats in each group. The hyperlipemia rat model was prepared by feeding high fat forage. The blank control group were fed by basic forage each day, and other 2 groups were fed with high fat forage each day. After the rats were fed for 2 weeks, EA was given at "Fenglong" (ST 40) in the rats of the Fenglong group, twice each week, for 10 times. At the end of EA treatment, SOD activities and MDA contents in the spleen, lung, liver and pancreas were detected.
Results: Acupuncture at "Fenglong" (ST 40) significantly increased SOD activities in the spleen and lung, decreased MDA content in the lung, and had a tendency to decrease SOD activity and to increase MDA content in the liver, while it did not significantly influence SOD activity and MDA content in the pancreas.
Conclusion: The target organs of "Fenglong" (ST 40) regulating SOD activity and MDA content are spleen, lung and liver, particularly, spleen and lung, with no relation with pancreas. It is indicated that the resolving phlegm function of "Fenglong" (ST 40) is related with promoting metabolism of free radiations in special organs.

Introduction: MRTX1133 is a selective and reversible small molecule inhibitor of KRAS (G12D), which significantly delays the progression of solid tumors. However, no study on the absorption, distribution, and excretion of MRTX1133.
Methods: A fast ultra-high performance liquid chromatography-tandem quadrupole mass spectrometry method was developed for the determination of MRTX1133 in rat plasma, tissue homogenate, and urine.
Spondylo-Thoracic Dysplasia: Survival, a Rare Occurrence.

Article Synopsis
- Spondylo-thoracic dysplasia (STD) is a rare congenital condition that affects the vertebrae and thoracic area, often leading to serious respiratory issues and a high risk of early death in neonates.
- The text details the case of a one-day-old male newborn with severe respiratory distress and various physical anomalies, including scoliosis and rib deformities, identified through clinical examinations and imaging studies.
- The baby was diagnosed with STD, received conservative management, and survived past the neonatal period, offering insights into this particular variant of the condition.

Article Synopsis
- B cells can be engineered to produce therapies for genetic disorders, metabolic diseases, and cancer.
- A method was developed to collect, expand, differentiate, and track B cells from non-human primates (NHPs) using radioactively labeled imaging techniques.
- The study showed that infused B cells successfully targeted the bone marrow, spleen, and liver without serious side effects, indicating the potential for repeated treatments and the viability of NHPs as a model for human B cell medicine research.
Etiological and histomorphological studies on early chick mortality in broiler chicken in Kashmir, India.

Background: Early chick mortality (ECM) is one of the most important problems of the poultry industry that causes severe economic losses to the farmers. The chick mortality varies in different geographical locations and its etiological factor also varies.
Aim: The aim of the present work was to isolate and identify various etiological agents responsible for causing ECM in broilers, and study the overall occurrence and pathology of various disease conditions responsible for causing ECM in broilers.
