The present study aimed to investigate the effects of treatment with thymosin α1 (TA1) or interferon α (IFNα) following the establishment of severe acute pancreatitis (SAP) in rats. A total of 144 Sprague‑Dawley rats were randomly divided into four groups. The rats in all four groups were celiotomized, and the rats in the control group were administered with an intravenous injection of saline. The three other groups were administered with 5% 1 ml/kg sodium taurocholate via the cholangiopancreatic duct. SAP group rats were administered with an intravenous injection of saline; TA1 group rats received 26.7 µg/kg TA1; and interferon α (INFα) group rats received 4.0x105 U/kg IFNα. The rats were anesthetized and blood samples were collected from the animals 3, 12 and 24 h after surgery. The levels of T cell subsets, serum enzyme indicators, cytokines and procalcitonin (PCT) were measured. The general conditions of the rats were observed until sacrifice, and pancreatic and lung tissue samples were sampled for hematoxylin and eosin staining and histological scoring. The expression levels of aspartate transaminase, lactate dehydrogenase, α‑amylase (AMY), P‑type‑amylase, lipase, PCT, tumor‑necrosis factor α, interleukin (IL)‑4, IL‑5, and IL‑18 in the TA1 and IFNα‑treated rats were significantly lower, compared with those of the SAP rats within the first 24 h of model establishment (P<0.05). The TA1 and IFNα‑treated rats exhibited significantly increased levels of CD3+, CD4+ and CD8+ T cells, and an increased ratio of CD4+/CD8+ cells, compared with SAP rats. Histological analysis revealed that the TA1 and IFNα‑treated rats exhibited significantly ameliorated pancreas and lung damage, and mortality rates were reduced from 50.0% (6/12) to 25.0% (3/12) and 33.3% (4/12), respectively. The immunomodulatory agents TA1 and IFNα reduced acute inflammation, decreasing cell damage and enhancing immune function and survival rates in the SAP rats.

Background: Post-surgical tendon adhesion formation is a frequent clinical complication with limited treatment options. The aim of this study is to investigate safety and efficacy of orally administration of crocin in attenuating post-operative tendon-sheath adhesion bands in an Achilles tendon rat model.
Methods: Structural, mechanical, histological, and biochemical properties of Achilles tendons were analyzed in the presence and absence of crocin.

Extensive uses of silver nanoparticles (Ag NPs) in different industries result in exposure to these nanoparticle imperatives in our daily lives. Resveratrol is found in many plants as a natural compound. The present study aimed to estimate the renal toxic effects of Ag NPs in adult male albino rats and the underlying relevant mechanisms while studying the possible role of resveratrol in ameliorating these effects.

Objectives: The significant correlation between acute myocardial infarction and subsequent hepatorenal dysfunction could result in a higher mortality rate in patients. The study aimed to evaluate the effect and mechanisms of coenzyme-Q10 (Q10) administration on hepatorenal dysfunction in an isoprenaline (ISO)-induced myocardial infarction model in rats.
Materials And Methods: Twenty male rats were assigned into four groups (n = 5).

The early treatment of Osteonecrosis of Femoral Head (ONFH) remains a clinical challenge. Conventional Bone Marrow Mesenchymal Stem Cell (BMSC) injection methods often result in unsatisfactory outcomes due to mechanical cell damage, low cell survival and retention rates, inadequate cell matrix accumulation, and poor intercellular interaction. In this study, we employed a novel cell carrier material termed "3D Microscaffold" to deliver BMSCs, addressing these issues and enhancing the therapeutic effects of cell therapy for ONFH.

Objectives: Both intrinsic and extrinsic factors cause skin aging. Intrinsic aging is characterized by decreased collagen density, particularly collagen types I (COL1A1) and III (COL3A1), and an increase in the COL1/COL3 ratio. Extrinsic aging, primarily due to ultraviolet light exposure, leads to photoaging, which causes collagen fragmentation and reduced production, leading to skin sagging.
