Comparison of Bran-Processed and Crude Atractylodes Lancea Effects on Spleen Deficiency Syndrome in Rats

Pharmacognosy Magazine
Dong-Hua XueXue Pang


The rhizome of Atractylodes lancea (AL) is usually used for the treatment of various diseases such as spleen deficiency syndrome (SDS). Both bran-processed and crude AL is included in Chinese Pharmacopoeia. The different efficacies of bran-processed and crude AL on SDS are largely unknown, and the mechanisms of AL effects have not been fully elucidated. The objective of the study was to compare the effects of bran-processed and crude AL and then assess the mechanisms of treating SDS. The model of SDS in rats was established using excessive exertion, combined with an irregular diet and intragastric administration of the extract of Sennae Folium, and different doses of bran-processed and crude AL were gavaged. The serum was analyzed by an enzyme-linked immunosorbent assay (ELISA), and small intestinal tissues were analyzed by reverse transcription-polymerase chain reaction (RT-PCR). The injury of SDS was alleviated by the treatment of bran-processed and crude AL. Compared to model group, the indexes of trypsin (TRY), amylase (AMS), vasoactive intestinal peptide (VIP), somatostatin (SS), gastrin (GAS), substance P (SP), Na+-K+-ATPase, and succinic dehydrogenase in serum of each administration group were increased by ELISA, and the...Continue Reading

Coronaviruses encompass a large family of viruses that cause the common cold as well as more serious diseases, such as the ongoing outbreak of coronavirus disease 2019 (COVID-19; formally known as 2019-nCoV). Coronaviruses can spread from animals to humans; symptoms include fever, cough, shortness of breath, and breathing difficulties; in more severe cases, infection can lead to death. This feed covers recent research on COVID-19.

Sexual Dimorphism in Neurodegeneration

There exist sex differences in neurodevelopmental and neurodegenerative disorders. For instance, multiple sclerosis is more common in women, whereas Parkinson’s disease is more common in men. Here is the latest research on sexual dimorphism in neurodegeneration
