Methimazole-induced hypothyroidism is a clinical problem in the treatment of hyperthyroidism in people and animals and is an example of metabolic disease that can lead to fertility disorders and can give elastographic testicular changes.

Material and Methods

Ultrasound elastography using the Esaote MyLab Twice ultrasound system and a morphological examination of testes were performed in seven methimazole-administered (group E) and seven healthy rats (group C).


The elasticity ratio of strains in the scrotal wall of the near-field test area to testicular tissue (ELX-T-RAT) and hardness percentage of strained tissues in the defined area of a testicle (ELX-T%HRD) in group E were statistically significantly lower than in group C. The degree of spermatogenesis was statistically significantly higher in group E than in group C and similarly seminiferous tubule diameters in group E were statistically significantly higher than in group C. Body weight and testicular weight in group E were statistically significantly lower than in group C.


Changes in the elastographical parameters of testes may result from disorders secondary to hypothyroidism. The usefulness of elastography is noteworthy in the case of evaluation of testis function in patients with some metabolic disorders.


The aim of the study was to optimise selected PCR methods for identification of T. solium, and to compare their effectiveness and usefulness. The investigation concerned three PCR methods described earlier: PCR I (specific to oncospherespecific protein Tso31 gene), PCR II (specific to large subunit rRNA gene), and PCR III (cytochrome c oxidases ubunit 1 gene). Each of them needed optimisation in connection with some changes in the procedures. Among the examined procedures, PCR I was found to be the most useful, requiring the least corrections during optimisation - only a higher concentration of polymerase was necessary. Testing an optimised PCR II method showed strong unspecific reactions with E. granulosus and T. saginata. This method was not considered diagnostically useful in distinguishing T. solium. PCR III method yielded products only when annealing temperature was lowered by 2 C. Under such conditions, there were no unspecific reactions with three others Taenidae parasites; however, annealing at a temperature only 1oC lower generated a distinct unspecific PCR product from T. saginata DNA. Therefore, this method was of limited usefulness. Comparison of the effectiveness of the two selected methods (PCR I and III) in detection of T. solium in successive DNA dilutions showed a large difference between them: in the same DNA sample, PCR I showed positive results in a sample diluted 1:3200, while PCR III failed at dilutions greater than 1:50. The results showed that among the three different methods used in the investigations, the most specific and effective for identification of T. solium was PCR I.


The paper describes the influence of oral administration of methimazole on biophysical skin parameters. Wistar rats of different sex (220-260 g) were used in the experiment. Biophysical skin parameters, such as transepidermal water loss (TEWL), corneometry, and pH were examined at seven-day intervals. Significant changes in the parameters were observed on the 7th d of methimazole administration. The changes were observed in both sex but males appeared to be less sensitive in that respect. Changes in the parameters in the females showed rapid mechanisms, which normalised transepidermal water loss and skin hydration, as well as restored skin barrier functions. TEWL, skin hydration, and skin pH measurements allow an early assessment of skin barrier dysfunction after administration of this drug.


The aim of the study was to assess the distribution of Anaplasma phagocytophilum, Borrelia burgdorferi sensu lato, and Babesia canis in adult females and males of Ixodes ricinus and Dermacentor reticulatus ticks, inhabiting meadows near large forest complexes throughout the Lubelskie Voivodship (eastern region of Poland). Ticks were collected using the flagging method. Among 720 ticks collected, 506 were identified as D. reticulatus, and 214 as I. ricinus. DNA of B. canis and B. burgdorferi s.l. was detected in 21.3% and 0.6% of D. reticulatus ticks, respectively. In I. ricinus ticks, DNA specific to B. burgdorferi s.l. and A. phagocytophilum was detected in 5.6% and 10.3%, respectively. Co-infections of B. burgdorferi s.l. and A. phagocytophilum were found in two I. ricinus ticks. These results indicate that the Lublin region is an area at risk of tick-borne diseases of humans and animals, which must be considered in clinical practice.
