In spite of technical advances in vaginal cytology (VC) and serum-progesterone (SP) assay, the challenges appeared not to have abated. Five clinical scenarios involving VC and SP are presented, aimed at investigating technique-performance and creating more robust awareness on application of SP titers obtained using a fluorescence immunoassay kit having 7.6–20.0 ng/mL as predictable-progesterone-titer-range-for-insemination-(PPTRi). Number of bitches, insemination-readiness-detection-technique(s) (IRDT), score (%) of agreement/disagreement between Insemination-readiness-detection techniques (SABT) for peculiarities of bred bitch(es) (PBB), proportion of bitches that became pregnant confirmed by relaxin assay and, number of pups littered were studied. Results obtained for number of bitches, IRDT, SABT or PBB, relaxin and number of pups littered, respectively were: 22, VC-SP, 81.8%/18.2%, 72.7% and, NA (i.e. not-available) (case I); 2, VC-SP, bitches mated after attaining PPTRi 10 and 13 days after been detected ready-for-mating via VC, 100%, and, 5 and 7, respectively (case II); 1, SP, bitch mated at SP of 4.401 ng/mL, 100% and, 11 (case III); 2, SP, first bitch mated at 4.682 ng/mL and the second at 7.049 ng/mL, 100% and, 9 and 12, respectively (case IV); 1, VC-SP, bitch mated once detected ready-for-mating by VC while SP at 24-hours post-mating was 2.852 ng/ mL, 100% and, 1 (case V). These findings suggest high-level agreement in accuracy of Insemination-readiness-detection between the two techniques, with none reflecting superiority. For better breeding successes, it is recommendable to inseminate earlier, during the peri-ovulation period.</p> Samuel Ayodele Famakinde, Oluropo Michael Obafemi, Tolulope Adeoye Ajayi, Olufisayo Oluwadamilare Leigh, Oreoluwa Raymond Akinbote, Adedamola O Olanrewaju, Deborah Boluwatife Ola, Oluwaseyi Oladiran Fakorede, Barakat Adedamola Salaudeen, Mutiat Busayo Rabiu Copyright (c) 2025 Samuel Ayodele Famakinde, Oluropo Michael Obafemi, Tolulope Adeoye Ajayi, Olufisayo Oluwadamilare Leigh, Oreoluwa Raymond Akinbote, Adedamola O Olanrewaju, Deborah Boluwatife Ola, Oluwaseyi Oladiran Fakorede, Barakat Adedamola Salaudeen, Mutiat Busayo Rabiu http://creativecommons.org/licenses/by-sa/4.0 https://e-journal.unair.ac.id/OVZ/article/view/55744 Tue, 01 Apr 2025 00:00:00 +0700 A study on the beneficial effect of advocating prophylactic spaying of young nulliparous bitches to prevent pyometra https://e-journal.unair.ac.id/OVZ/article/view/70079 <p>This study aimed to evaluate the potential benefits of advocating elective spaying (ES) in young nulliparous bitches as a preventive measure for pyometra, a severe and potentially life-threatening condition. Specifically, the study examined whether elective spaying, which eliminates the risk of pyometra and its associated complications, offers significant advantages over the treatment of pyometra once it develops. Generally, the short- and long-term risks associated with elective spaying are minimal when compared to the significant complications and dangers posed by pyometra. A retrospective open-ended study was conducted, collecting data from veterinary clinics across Penang Island using a structured questionnaire. Information was gathered primarily from medical records and interviews with veterinarians and pet owners when data were missing or unclear in the records. The study compared 30 bitches of various breeds who underwent elective spaying with 30 bitches who underwent emergency ovariohysterectomy (EOH) due to pyometra. A standard set of outcomes was evaluated to assess and compare complications. The results showed that the elective spaying group experienced only minor or trivial complications, and owners incurred significantly lower costs compared to those whose bitches underwent emergency surgery for pyometra, which was associated with more severe complications and substantially higher costs. Based on these findings, the study concluded that elective spaying is a safe and cost-effective prophylactic measure against pyometra.</p> Sharveihn Sathindren, Suryo Kuncorojakti, Suzanita Utama, Tita Damayanti Lestari, Wiwik Misaco Yuniarti Copyright (c) 2025 Sharveihn Sathindren, Suryo Kuncorojakti, Suzanita Utama, Tita Damayanti Lestari, Wiwik Misaco Yuniarti http://creativecommons.org/licenses/by-sa/4.0 https://e-journal.unair.ac.id/OVZ/article/view/70079 Tue, 01 Apr 2025 00:00:00 +0700 Synergistic protective effects of α-tocopherol and zinc sulfate on superoxide dismutase activity and p53 expression in ovarian granulosa cells of lead-exposed female Wistar rats (Rattus norvegicus) https://e-journal.unair.ac.id/OVZ/article/view/62786 <p>This study aimed to evaluate the protective effects of α-tocopherol and zinc sulfate on oxidative stress parameters in ovarian granulosa cells of female Wistar rats (<em>Rattus norvegicus</em>) exposed to lead acetate (Pb(C₂H₃O₂)₂). A total of 25 rats were randomly divided into five groups: Control (C), lead exposure only (T0), α-tocopherol + lead (T1), zinc sulfate + lead (T2), and α-tocopherol + zinc sulfate + lead (T3). Treatments were administered orally for 21 days. Superoxide dismutase (SOD) levels were measured spectrophotometrically, and p53 expression was analyzed using immunohistochemistry. The results showed that SOD levels significantly decreased in group T0 compared to the control (p &lt;0.05), while treatment with either α-tocopherol (T1), zinc sulfate (T2), or their combination (T3) significantly improved SOD levels compared to T0. Moreover, p53 expression was markedly elevated in T0, indicating enhanced oxidative stress and potential apoptosis, whereas all antioxidant-treated groups showed reduced p53 expression, with T3 demonstrating values comparable to the control group. In conclusion, the combination of α-tocopherol and zinc sulfate provided a synergistic antioxidant effect, effectively enhancing SOD levels and suppressing p53 expression in granulosa cells of lead-exposed rats. This suggested a promising therapeutic potential of these compounds in mitigating lead-induced ovarian toxicity.</p> iqbal dwi warsito, Suherni Susilowati, Erma Safitri, Ragil Angga Prastiya, Maya Nurwartanti Yunita, Amung Logam Saputro Copyright (c) 2025 iqbal dwi warsito, Suherni Susilowati, Erma Safitri, Ragil Angga Prastiya, Maya Nurwartanti Yunita, Amung Logam Saputro http://creativecommons.org/licenses/by-sa/4.0 https://e-journal.unair.ac.id/OVZ/article/view/62786 Tue, 01 Apr 2025 00:00:00 +0700
