The reasons reduction and replacement of laboratory animals are advancing rapidly in basic biomedical research, and why in industrial toxicology progress is much slower, are analyzed. Reference is made to a previous report from our laboratory, and the general concept of the program is outlined. Encouraging developments concerning acceptance of new concepts in acute toxicity testing by various regulatory agencies are reviewed (OECD, IKS,
EEC
, and Bureau of Pharmaceutical Affairs, Ministry of Health and Welfare, Japan). On the basis of new concepts proposed by the British Toxicology Society, a program which attempts to evaluate acute toxicity of chemicals as far as possible without causing mortality was started. Continuous in-
cage
monitoring of motility of animals, regular control of general health, body weight, food and water consumption, and body temperature are used as variables. The possibilities of reducing animal use in toxicology by application of toxicological screening procedures are explained. Screening tests under development include an operant conditioning technique to detect adverse drug interactions with ethanol and a procedure for the detection of nephrotoxic properties. The successful completion of a collaborative program designed to upgrade toxicity testing with contraceptive steroids and to abolish the 7-year beagle and 10-year monkey studies is reported. The application of in vitro cytotoxicity tests for assessment of irritant and corrosive properties of chemicals is discussed and some encouraging progress on regulatory acceptance of such tests (OECD) is reported. A new test developed at the institute is described. An in vitro model for the investigation of chemically induced changes of collagen synthesis in human fibroblasts is presented. Other cell culture methods under development include a culture system of chick brain, retina, and menings cells for the study of neurotoxic chemicals and neurobehavioral teratogens, primary hepatocyte cultures for the study of drug effects on DNA and protein synthesis and ploidy, using flow cytometry, and various in vitro models for the assessment of genotoxic and tumor-promoting activities and malignant cell transformation. The problem of analgesic treatment of animals with chronic pain was investigated. Several analgesics were evaluated, and treatment modalities providing demonstrable analgesia for prolonged periods of time in mice and rats were worked out.

For evaluation of the possible risk of drugs and chemicals for the human organism and its vital functions and to detect possible undesirable action on the environment, laboratory animals must be used. In toxicology as biomodels standard strains, as regards genetic and health aspects, mice, rats, rabbits, guinea pigs and dogs are used. The basis of standardization of conditions for keeping laboratory animals is as regards physical, chemical and biological aspects adherence to conditions of the adopted regulations of the Council of European Communities of Nov. 24, 1986. Council Directive 86/609/
EEC
, known in this country as the "Strasbourg convention". Part of the protection of laboratory animals used for experimental and other scientific purposes is also the adherence to the optimal number of animals as regards the area or
cage
where they are kept as well as the cubic measure of the space. Standardization of scientific results is promoted also by adherence to transport conditions of the animals, the time of acclimatization, quarantine. Knowledge of the basic biology of laboratory animals used should be obvious for experimental workers. All work on animals must be governed by valid laws and instructions which make work with animals possible. In the Czech Republic its is the act of the Czech National Council No. 246 issued in 1992 for the protection of animals from maltreatment according to which work with animals can be carried out only by institutions with accreditation for the given work which moreover have an ethical commission which issues permission for work with animals.(ABSTRACT TRUNCATED AT 250 WORDS)

It is now more than 20 years since both Council of Europe Convention ETS123 and EU Directive 86/609/
EEC
were introduced, to promote the implementation of the Three Rs in animal experimentation and to provide guidance on animal housing and care. It might therefore be expected that reports of the implementation of the Three Rs in animal research papers would have increased during this period. In order to test this hypothesis, a literature survey of animal-based research was conducted. A randomly-selected sample from 16 high-profile medical journals, of original research papers arising from European institutions that featured experiments which involved either mice or primates, were identified for the years 1986 and 2006 (Total sample = 250 papers). Each paper was scored out of 10 for the incidence of reporting on the implementation of Three Rs-related factors corresponding to Replacement (justification of non-use of non-animal methods), Reduction (statistical analysis of the number of animals needed) and Refinement (housing aspects, i.e. increased
cage
size, social housing, enrichment of
cage
environment and food; and procedural aspects, i.e. the use of anaesthesia, analgesia, humane endpoints, and training for procedures with positive reinforcement). There was no significant increase in overall reporting score over time, for either mouse or primate research. By 2006, mouse research papers scored an average of 0 out of a possible 10, and primate research papers scored an average of 1.5. This review provides systematic evidence that animal research is still not properly reported, and supports the call within the scientific community for action to be taken by journals to update their policies.

The two most frequent types of endometrial cancer (EC) are endometrioid (
EEC
) and serous carcinomas (SC). Differential diagnosis between them is not always easy. A subset of endometrial cancers shows misleading microscopical features, which cause problems in differential diagnosis, and may be a good scenario for next-generation sequencing. Previous studies have assessed the usefulness of targeted sequencing with panels of generic
cancer-associated
genes in EC histological typing. Based on the analysis of TCGA (The Cancer Genome Atlas),
EEC
and SC have different mutational profiles. In this proof of principle study, we have performed targeted sequencing analysis with a customized panel, based on the TCGA mutational profile of
EEC
and SC, in a series of 24 tumors (16
EEC
and 8 SC). Our panel comprised coding and non-coding sequences of the following genes: ABCC9, ARID1A, ARID5B, ATR, BCOR, CCND1, CDH19, CHD4, COL11A1, CSDE1, CSMD3, CTCF, CTNNB1, EP300, ERBB2, FBXW7, FGFR2, FOXA2, KLLN, KMT2B, KRAS, MAP3K4, MKI67, NRAS, PGAP3, PIK3CA, PIK3R1, PPP2R1A, PRPF18, PTEN, RPL22, SCARNA11, SIN3A, SMARCA4, SPOP, TAF1, TP53, TSPYL2, USP36, and WRAP53. Targeted sequencing validation by Sanger sequencing and immunohistochemistry was performed in a group of genes. POLE mutation status was assessed by Sanger sequencing. The most mutated genes were PTEN (93.7%), ARID1A (68.7%), PIK3CA (50%), and KMT2B (43.7%) for
EEC
, and TP53 (87.5%), PIK3CA (50%), and PPP2R1A (25%) for SC. Our panel allowed correct classification of all tumors in the two categories (
EEC
, SC). Coexistence of mutations in PTEN, ARID1A, and KMT2B was diagnostic of
EEC
. On the other hand, absence of PTEN, ARID1A, and KMT2B mutations in the presence of TP53 mutation was diagnostic of SC. This proof of concept study demonstrates the suitability of targeted sequencing with a customized endometrial cancer gene panel as an additional tool for confirming histological typing.
