Opis:
The authors treated 15 students (Asia, Africa) infected with Hymenolepis nana, using a single dose of praziquantel Biltricid of 30 mg/kg b.w., administered as two portions 15 mg/kg b.w. each, with an interval of 6 hrs. After two months the parasites were found to be absent in 13 persons (86.7%). The tolerance for Biltricid was found to be good, though an ultimate answer to the question of its medical application requires further studies.

Opis:
Contemporary methods of directed chemotherapy are based on multi-step procedures, which require co-ordinated activities of interdisciplinary teams of biochemists, pharmacologists, geneticists, crystallochemists as well as computer scientists. Biochemists select the proper target, such as an enzyme, througt screenig of the biochemical influence of compounds-potential drugs on this target. For further research they use targets with very low inhibition constans ( > 10⁻⁶ M). Determination of the relation between therapeutic activity of the compound and modelling of its chemical structure constitutes an important part of the procedure. The most important part of the procedure is the recognition of the primary structure of the target. The two following pathways allow to do that: 1. isolation of DNA and gDNA or cDNA-started cloning of a gene responsible for production of the target protein and then its sequencing, 2. purification and crystallization of the target protein and further computer-aided processing of crystallographic data in order to determine the primary structure. Computational chemistry (C/C) methods are the basic part of the procedure of molecular modelling (M/M) of a target molecule and its interactions with a molecule of the future drug. Data obtained using a technology which engages the C/C and M/M methods not only allow to determine the aminoacid sequence of the target protein in question (e.g. a unique parasite enzyme) they also enable to further speculate on its secondary and tertiary structures. Such structure includes specified number of repeated motifs of α-helixes, β-sheets and loops or turns. Particularly, the „barrel" structure is very common in numerous enzymes. Two following examples of research on target-antiparasitic drug interactions is presented. They are the interaction between phosphoglicerate kinase in Leishmania and drug suramin and malic enzyme of Trichinella and drug closantel. New promising targets for new anti-protozoan drugs (protozoa of Trypanosoma species) include e.g. microbody translocation signal in kinetosom proteins (SKL) or protein blocking the transport of proteins to glycosomes-metabolic centres in Trypanosoma (repetitive groups of QRLQ). Recently, scientists Crom Arris Pharmaceutical (San Francisco) have considered, employing new data, up to 100 to fully characterize the surface structure of a molecule, using the systems of artificial intelligence.

Opis:
Research into changes in the activity and kinetics of the reaction catalysed by the important detoxificating enzyme, glutathione-S-transferase (GST), in the intestinal phase of trichinellosis as presented in the present study is a pioneering achievement. In every instance of infection – or if infection is only suspected – the patient receives anthelmintics that are effective against mature intestinal forms, newborn larvae and encysted larvae of Trichinella spiralis. This group of drugs includes benzimidazoles such as albendazole. The primary action of these drugs concerns β-tubuline. The functions of microtubules are damaged by bonding β-tubuline with benzimidazoles, which inhibits the polymerisation of microtubules. Newly considered fields of action of benzimidazoles on the pathological changes occurring in the host during the course of parasitic diseases are the following elements taking part in the immunological defence against a parasitic infection: for example, detoxificating enzymes such as glutathione-Stransferase (GST), and Toll-like receptors (TLRs). Occurrence of cell resistance to drugs is attributed to certain enzymes, (such as GST), which perform the detoxification of these drugs and facilitate their removal from cells through a pump dependent on compounds coupled with glutathione. In the case of the intestinal phase of trichinellosis, GST may remove toxins secreted by both the adult and newborn larvae of T. spiralis. The structure of a dimeric enzyme of the host, such as GST, may be impacted by various factors, for example excretory-secretory products (ES), as well as drugs used. Over the past few years, the interest of researchers in the innate immune response as the first line of defense of vertebrates against of pathogens, was increased. The number of works devoted to the role of Toll-like receptors, which enable the immediate commencement of protective action by the host against various infections without engaging lymphocytes, is on the noticeable. The experimental material consisted of small and large intestine from BALB/c mice infected with T. spiralis strain MSUS/PO/60/ISS3. Mice were inoculated orally with about 400 T. spiralis larvae per mouse. On the 2nd day post-infection, the mice were treated with albendazole, in a dose of 0.5 mg/mouse. The activity and kinetics of the GST were determined spectrophotometrically. An evaluation of the expression of TLRs (TLR2 and TLR4 on the mRNA level) was examined using the RT-PCR technique with the appropriate starter sequences for TLR2 and TLR4. The presence of Toll-like receptors and their expression on the protein level was confirmed using the immunohistochemical method (Santa Cruz ABC Stainig system sc-2023 test) with specific polyclonal antibodies antiTLR2 and anti-TLR4. My results pointed to the participation of GST, as well as Toll-like receptors, in defence processes of the host during the intestinal phase of trichinellosis in mice. The adult and newborn larvae of T. spiralis present in the intestines of infected mice are a source of excretory-secretory (ES) products, which appear to stimulate the activity and change catalytic properties of conformers GST. It is supposed that ES products secreted by the parasite acts on GST as an allosteric activator. Additionally, the presence of Toll-like receptors (TLR2 and TLR4) in the intestinal phase of trichinellosis was investigated. Thus, the infection with T. spiralis leads to strong biochemical reactions with the involvement of GST, and immunological reactions with the involvement of TLR2 and TLR4 receptors. Administration of albendazole, resulted in 2-fold decrease of the total activity of GST in comparison with its activity in infected and untreated animals. Also, drug administration had weakened expression of gene of TLR4 and TLR2 in the large intestine, and expression of gene of TLR2 in the small intestine. My results confirmed destructively action of albendazole on T. spiralis (resulted in 4-fold decrease in the intensity of infection measured in muscles). The destruction by the drug of a adult and newborn larvae of T. spiralis lowers the quantities of their ES products stimulated the activation of the host’s response. This is apparent as weakening the innate immune response, in which take part Toll-like receptors play a role, and in biochemical processes with the participation of the GST enzyme. In summary my results contribute new data on the participation of Toll-like receptors and GST in the defence mechanisms of the host during in the intestinal phase of experimental trichinellosis in mice.

Opis:
The authors used Albendazole in a single dose of 400 mg in 40 students from Africa and Asia, infected with Ascaris lumbricoides, Trichocephalrus trichiurus and Ancylostomatidae. At the third day after the treatment no parasite eggs have been found in 25 of 30 cases of ancylostomatidosis (83.3%), 16 of 23 cases of trichocephalosis (69.6%) and in all treated cases of ascaridosis (100%). It has been also found that the tolerance for the medicine is good in most patients. Only in two patients (2%) there appeared short time and not very strong pains in the upper part of the abdomen and headaches. An important property of Albendazole is its ability to destroy nematode eggs which is essential for the prophylaxis and nature conservation.
