4. Legislation on the protection of experimental animalsDragica Ornik, Milan Pogačnik, 2001, pregledni znanstveni članek Povzetek: The aim of this paper is to establish the current situation in the field of legislation on the protection of experimental animals in Slovenia. The protection of experimental animals has been regulated by the provisions of theProtection of Animals Act.1 On the basis of this act, the Instructions on Conditions for the Issuing of Authorisations for Experiments on Animals for Scientific and Research Purposes2 and the Rules on the Ethics Commission for Experiments on Animals 3 have been used. The basic protection of experimental animals is provided for by a system of permits for experiments on animals. Permits for experiments on animals are granted by the administrative authorities responsible for veterinary medicine in cases where experiments areurgently required for medical, veterinary medical, or scientific and research purposes and the results are expected to produce important new knowledge, or when the suffering of animals is ethically acceptable in comparison with what the experiment is expected to achieve; where, in cases ofbasic research, experimental aims cannot be achieved by any other method or procedure, the experiment is performed on the minimum possible number of animals of the lowest neurophysiological sensitivity and a method is used thatcauses the minimum level of suffering, pain or lasting harm. Staff involved in the execution of experiments or in the care and nursing of animals, the premises for the accommodation or rearing and provision of animals, and the installations and devices used must all comply with the set conditions.

5. Upgrading of gamma cameras for developing countriesValentin Fidler, Milan Prepadnik, Yanfen Xie, 2001, izvirni znanstveni članek Povzetek: Background. The project of upgrading the analog gamma cameras with PC based systems from International Atomic Energy Agency (IAEA) and the Ministry of Science and Technology of RS is presented from the initial basic demands to the final developments. Several national research groups (from China, India, Cuba and Slovenia) were involved in the IAEA development project for the acquisition card with software and the standard set of clinical protocols. Conclusions. The most functionally stable acquisition system tested on severalinternational workshops and in university clinics was the Slovenian onewith a complete set of nuclear medicine clinical protocols, documenting, networking and archiving solutions for simple MS Network or server oriented network systems (NT server, etc). More than 300 gamma cameras in 52 countries all over the world were digitized and put in routine clinical work.

6. Ultrasound-guided aspiration biopsy of subclinical regional metastases of head and neck carcinomaAlenka Višnar-Perovič, Aleksandar Aničin, Živa Zupančič, Bojana Černelč, Alojz Šmid, Dubravka Vidmar, Milan Gorenc, 2000, izvirni znanstveni članek Povzetek: Background. Studies concerned with the estimation of ultrasound (US) combined with ultrasound-guided aspiration biopsy (USGAB) in the detection of subclinical regional metastases from the planocellular carcinoma of head and neck are promising, but in few cases. Recently, the authors have pointed out the role of lymph node size parameters in order to decide about the use of USGAB. The aim of this study was to test the reliability of US-USGAB for the detection of subclinical regional metastases in patients with planocellular head and neck carcinomas, including the evaluation of lymph node size parameters. Patients and methods. 121 neck sides with no palpable metastases were examined by US in 77 patients with planocellular carcinomas of head and neck. Depending on the results obtained, USGAB was performed on 64 neck sides.After surgery, the results of US-USGAB were compared with histological findings of the dissected lymph nodes. Results. The study showed 77% overall sensitivity of US and USGAB, and 100% specificity, while the versal / longiyudinal diameter was the best predictor of metastatic lymph node involvement. Conclusion. The results of this study established that USGAB is an appropriate method for detection the subclinical regional metastases on neck, and should be included into routine diagnostic work up in the evaluationof the extent of head and necks carcinomas.

10. Corrosion properties of aluminized 16Mo3 steelBlaž Karpe, Klara Prijatelj, Milan Bizjak, Tadeja Kosec, 2023, izvirni znanstveni članek Povzetek: Chromium-molybdenum steel (16Mo3) is widely used in petroleum, gas, automotive, and construction industries due to its good oxidation resistance and mechanical properties at moderately elevated temperatures. The aim of the research was to evaluate the corrosion susceptibility of 16Mo3 steel in hot rolled and aluminized states. Aluminization was performed by diffusion pack aluminization process at 900°C/2h and 730°C/4h, respectively. Electrochemical corrosion testing included measuring open circuit potential (EOCP), linear polarization resistance (LPR), potentiodynamic polarization, and electrochemical impedance spectroscopy (EIS) in potassium phosphate buffer (KH2PO4, pH = 7). Optical microscopy (OM), scanning electron microscopy (SEM), and energy dispersive X-ray spectroscopy (EDS) were used for surface layer microstructure characterization before and after corrosion tests. It was demonstrated that corrosion resistance of aluminized steel increased substantially. Corrosion properties were related to the structure and properties of intermetallic phase (FeAl, FeAl2 and Fe2Al5) that formed on the surface of 16Mo3 steel.
