The article discusses insect stings. The Schmidt Sting Pain Index, made by toxinologist Doctor Justin Schmidt, ranks stings from one to four. Schmidt's method involves obtaining sheila insect specimens, getting a guinea pig, and persuading the critter to sting. Schmidt suggests the use of ice and beer to numb one who has been stung. Among the insects that can sting are the European Paper Wasp, the American Tarantula Hawk Wasp, and the Brazilian Bullet Ant.

The article discusses a research paper by researcher Amichai Labin from Technion—Israel Institute of Technology in Haifa, Israel on how our normal eye forms images clearly with the help of Müller cells . Topics include the functioning of a kind of retinal glia known as Müller cells that channels light to the photoreceptors, the finding of the research carried out on guinea pig retinas and how the research could eventually help design better cameras and biomimetic sensors.

A recent study conducted by the University of Agricultural Sciences in Cluj Napoca, Romania, examined the effectiveness of afoxolaner (NexGard) in treating Trixacarus caviae, a sarcoptic mange mite that infests guinea pigs. The study found that a single oral dose of afoxolaner was safe and effective in treating the infestation, resulting in the complete remission of clinical signs and the absence of mites after four weeks. This research provides valuable insights into the treatment options for this condition, which can cause severe dermatological problems in guinea pigs. [Extracted from the article]

This study was undertaken to evaluate possible antiallergic effects of an extract of pigments from green sea urchin (Strongylocentrotus droebachiensis) shells. Effects were studied on animal models -- guinea pig ileum contraction, rabbit eyes allergic conjunctivitis, and rabbit local skin irritation. The extract significantly reduced, in a dose-dependent manner, the histamine-induced contractions of the isolated guinea pig ileum with ID50 = 1.2 μg/mL (in equivalents of spinochrome B), had an inhibitory effect on the model of ocular allergic inflammation surpassing the reference drug olopatadine, and did not show any irritating effect in rabbits. The extract predominantly contained polyhydroxy-1,4-naphthoquinone which would be responsible for the pharmacological activity. The active compounds of the extract were evaluated in silico with molecular docking. Molecular docking into H1R receptor structures obtained from molecular dynamic simulations showed that all spinochrome derivatives bind to the receptor active site, but spinochrome monomers fit better to it. The results of the present study suggest possibilities for the development of new agents for treating allergic diseases on the base of pigments from sea urchins shells. [ABSTRACT FROM AUTHOR]

Clematichinenoside is a triterpenoid saponin isolated from the roots of Clematis chinensis. Oxidative stress and excessive nitric oxide production are thought to play considerable roles in ischemia/reperfusion injury that impairs cardiac function. The present study investigated the protective effect of clematichinenoside on regional and global ischemia/reperfusion injury and ventricular myocytes. In vivo, regional myocardial ischemia/reperfusion injury of rats was induced by the occlusion of the left anterior descending coronary artery, and isolated guinea pigs heart using Langendorff apparatus served as a global ischemia/reperfusion injury model ex vivo. Primary cultured neonatal ventricular myocytes were further applied to explore the anti-ischemia/reperfusion injury property in vitro. Infarct size was measured with TTC stain; enzyme activities such as lactate dehydrogenase, creatine kinase, superoxide dismutase, malondialdehyde, and nitric oxide were analyzed with assay kits; inducible nitric oxide synthase and endothelial nitric oxide synthase expressions were determined by Western blot. Clematichinenoside attenuated infarct size, decreased lactate dehydrogenase, creatine kinase, and malondialdehyde levels and enhanced superoxide dismutase activity. Clematichinenoside improved hemodynamics indexes, such as left ventricular developed pressure, maximum left ventricular developed pressure, and increase/decrease rate (± dp/dtmax) in the isolated guinea pig heart after reperfusion. Clematichinenoside also inhibited excessive production of nitric oxide through downregulating inducible nitric oxide synthase as well as upregulating endothelial nitric oxide synthase during ischemia/reperfusion injury. Clematichinenoside attenuates ischemia/reperfusion injury in vivo, ex vivo, and in vitro via an antioxidant effect and by restoring the balance between inducible nitric oxide synthase and endothelial nitric oxide synthase.

Xue-Sai-Tong injection, a traditional Chinese medicine with total saponins of Sanqi ginseng as active ingredients, has been used for more than 500 years to treat coronary artery disease in China. Anaphylactoid reaction induced by Xue-Sai-Tong injection was one of the main adverse drug reactions which has occurred frequently in recent years. It is of importance to elucidate its anaphylactoid constituents. The in vivo anaphyalctoid tests indicated that the anaphylactoid mediators could be used as indexes to evaluate the anaphylactoid action. Further, the in vitro model based on determining the mediators release from the degranulation of mast cells and RBL-2H3 cells stimulated by Xue-Sai-Tong injection was explored. Mediators released from mast cells and RBL-2H3 cells caused by Xue-Sai-Tong injection were determined by comparison of the methods of fluorospectrophotometry, ELISA, and spectrophotometry, respectively, revealing that the histamine release induced by the Xue-Sai-Tong injection could not be assayed accurately by the method of fluorospectrophotometry because of the interference of saponins and unknown components in the injection. The rat peritoneal mast cell was also not an optimal cell model for determining histamine and β-hexosaminidase release due to the higher spontaneous release ratio during the cell collection. Thus, ELISA determination of the histamine release from RBL-2H3 cells is a suitable in vitro model to assay the anaphylactoid reaction of Xue-Sai-Tong injection. Previously, abnormal hemolysis in some batches of Xue-Sai-Tong injectionwas observed in the course of their HD50 (half hemolytic dosage) determination. This study further found that injections which exhibited an abnormal hemolysis phenomenon also caused a higher release of the anaphylactoid mediators from RBL-2H3 cells, indicating the HD50 could be an auxiliary index to evaluate anaphylactoid action of the herbal injection indirectly. Research for anaphylactoid components in Xue-Sai-Tong injection indicated that proteins with over 10 KDa of molecular weight, but not ginsenosides, could be the main constituents inducing the release of anaphylactoid mediators from RBL-2H3 cells. An HPLC method for protein determination in the Xue-Sai-Tong injection was established subsequently, and the content of proteins with molecular weights of over 10 KDa in the injections showed an obviously positive correlation with the histamine release induced by the injections. In addition, taking ginsenoside-Rd coupled with BSA as an example, the hapten property of ginsenosides was studied and the ratio of ginse-noside-Rd to BSA was determined to be 8:1 by matrix-assisted laser desorption/ionization time-of-flight mass spectrometry, and the ginsenoside-BSA conjugate showed a stronger action to stimulate histamine release from the RBL-2H3 cells.

Three new indole alkaloids, named kopsihainins A-C (1-3), and two known compounds, kopsinine (4) and methyl demethoxycarbonylchanofruticosinate (5), were isolated from the stems of Kopsia hainanensis. Their structures were determined using extensive spectroscopic methods. The two main constituents 4 and 5 exhibited significant antitussive activity in a citric acid induced guinea pig cough model. The antitussive effect of 4 was demonstrated to interact with the δ-opioid receptor. This is the first report of antitussive effects of aspidofractinine type and chanofruticosinate type alkaloids.

A study conducted at the University of Leipzig in Germany evaluated neurological testing in guinea pigs. The researchers performed neurological examinations on 25 guinea pigs and assessed the feasibility, reproducibility, and stress levels associated with each test. The study found that several neurological tests can be applied to guinea pigs and produce meaningful results, providing a possible protocol for neurological examination in these animals. The results of this study could contribute to a better understanding of lesion localization and guide diagnostic and therapeutic approaches for guinea pigs with neurological diseases.
