Mice given a killed suspension of Corynebacterium parvum (C.p.) developed nephritis as part of an immune complex disease. The nephritis was dose-related. After a single dose of 70 microgram (a human-equivalent dose) or of 466 microgram there was a mesangiopathic glomerulonephritis and after repeated human-equivalent doses there was a mesangiocapillary glomerulonephritis. Antibodies to C.p. increased and circulating immune complexes were detected. Mice receiving repeated doses also developed an arteritis. Study of this model may help in the understanding of human immune complex disease and the pathogenesis of glomerulonephritis.

Antibiotic resistance is recognized as one of the top ten global public health threats, posing a significant challenge to human health. The stereochemistry of chiral molecules, alongside their specific interactions with biological targets, provides essential insights for the development of novel antibacterial agents, This study investigated the antibacterial activity of 32 previously synthesized 14-position chiral matrine derivatives. Among these derivatives, compound Q4 exhibited the strongest activity against Propionibacterium acnes, with a minimum inhibitory concentration (MIC) of 0.
