Therapeutic effects of lincomycin and level of drug degradation in broiler tissues after treatment

Background and Aim: Lincomycin is an antibiotic used in broiler farming and is commonly combined with other substances to achieve synergistic and complementary effects on the antibacterial spectrum and mechanism. We developed a specific high-performance liquid chromatography (HPLC) method to measure lincomycin levels in broiler tissues. This study aimed to determine the lincomycin level in tissues and compare it with the minimum inhibitory concentration (MIC) and maximum residue limit (MRL) of certain pathogenic bacteria. Materials and Methods: Three groups of broiler chickens were involved in the study (n = 20 in each group): A control group without lincomycin treatment and two groups (each further divided into two sub-groups) that received oral lincomycin at a dose of 1 g/10 kg of body weight daily for 7 and 14 consecutive days. Tissue samples were collected from each group 1 day and 1 week after lincomycin administration (ALA). This study validated the development of a technique for analyzing drug level degradation in tissues using HPLC. Descriptive and statistical analyses were performed for drug levels to assess their therapeutic value and safety based on lincomycin MIC of certain pathogenic bacteria and MRL. Results: The method validation resulted in linear regression and coefficient of determination for tissues with r2 > 0.99, with a recovery rate of 90%–110%, precision as the coefficient of variation 15%, and specificity with no peak overlap for lincomycin. The limits of detection for the liver and kidney were 0.01 μg/g, 0.05 μg/g, and 0.1 μg/g for the breast muscle and all tissues. Administration of lincomycin for 7 and 14 days resulted in therapeutic value concentrations. Lincomycin levels in the liver and kidney of ALA exceeded the MRL, whereas breast muscles were below the MRL for a week of ALA treatment. Conclusion: Administration of lincomycin for 7 and 14 consecutive days resulted in therapeutic value; however, after a week, most tissues showed high drug concentrations that exceeded the MRL. It is necessary to carefully consider the prolonged therapeutic dose of lincomycin in broilers. Antibiotic therapy must be guided in such a way as to protect the product from harmful residues. Keywords: : broiler tissues, lincomycin level, maximum residue limit, minimum inhibitory concentration.

Comparative evaluation of liquid-liquid extraction and nanosorbent extraction for HPLC-PDA analysis of cabazitaxel from rat plasma

A precise, sensitive, accurate, and validated reverse-phase high-performance liquid chromatography (RP-HPLC) method with a bioanalytical approach was utilized to analyze Cabazitaxel (CBZ) in rat plasma. Comparative research on extraction recoveries was performed between traditional liquid-liquid extraction (LLE) and synthesized graphene oxide (GO) based magnetic solid phase extraction (GO@MSPE). The superparamagnetic hybrid nanosorbent was synthesized using the combination of iron oxide and GO and subsequently applied for extraction and bioanalytical quantification of CBZ from plasma by (HPLC-PDA) analysis. Fourier- transform infrared spectroscopy (FT-IR), particle size, scanning electron microscopy (SEM), and x-ray diffraction (XRD) analysis were employed in the characterization of synthesized GO@MSPE nanosorbent. The investigation was accomplished using a shim pack C18 column (150 mm×4.6 mm, 5 µm) with a binary gradient mobile phase consisting of formic acid: acetonitrile: water (0.1:75:25, v/v/v) at a 0.8 mL/min flow rate, and a λmax of 229 nm. The limits of detection (LOD) and quantitation (LOQ) have been determined to be 50 and 100 ng/mL for both LLE and SPE techniques. The linearity range of the approach encompassed from 100 to 5000 ng/mL and was found to be linear (coefficient of determination > 0.99) for CBZ. The proposed method showed extraction recovery of 76.8–88.4% for the synthesized GO@MSPE and 69.3–77.4% for LLE, suggesting that the proposed bioanalytical approach was robust and qualified for all validation parameters within the acceptable criteria. Furthermore, the developed hybrid GO@MSPE nanosorbent with the help of the proposed RP-HPLC method, showed a significant potential for the extraction of CBZ in bioanalysis.

The Effect of Spiritual Therapy Intervention on The Risk Mental Health Disorders Among Flood Victims

Introduction: Disasters have diverse effects on various aspects of life, particularly on the psychological well-being of affected individuals. Victims of disasters often experience anxiety, trauma, stress, fear, and even prolonged sadness. For example, the flood disaster that occurred in Mukim Sri Medan, Batu Pahat, Johor, in 2023 is believed to have adversely affected the mental health of the affected community. Therefore, there is a need for strategies to address these mental health disruptions, and one potential approach is spiritual therapy. Objective: This research aims to assess the post-disaster mental health status of flood victims and analyze the influence of spiritual therapy on the mental health risk of flood victims in Mukim Sri Medan, Batu Pahat. Methods: This study adopts a quantitative approach using survey methods and questionnaires as research instruments. The target population includes individuals who were flood victims in Mukim Sri Medan, Batu Pahat. The sample consists of 207 respondents selected through non-probability sampling techniques, specifically accidental sampling. Data collection was conducted through a survey using questionnaires distributed to 207 respondents in the Mukim Sri Medan area. Data analysis employed multiple linear regression tests, correlation and determination coefficient tests, T-tests (partial), F-test (simultaneous), and descriptive analysis. Results and Conclusion: Research findings indicate that the majority of the post-flood mental health status of the community is high, with an overall mean score of 3.67. Spiritual therapy has a strong correlation with the post-disaster mental health of flood victims, with a significant value of 0.004b < 0.05, and a calculated t-value of 2.928 > t table 1.971, exerting an influence of 50.0%. Originality/Value: This study provides us with insights into the importance of maintaining inner strength in facing various disasters, especially floods, by engaging in therapy, whether it be mental therapy or spiritual therapy. Without therapy within oneself, the likelihood of mental health being affected, especially when confronted with the calamity of a disaster, is high.
