Objective: To determine the effectiveness of dexmedetomidine on the spinal anaesthesia as an adjuvant to the hyperbaric levobupivacaine in patients undergoing cesarean section. Study Design: Comparative/Observational Place & Duration: The study was conducted at Anesthesiology/Obstetrics and Gynaecology departments of Mayo hospital, Lahore for duration of six months i.e from 1st November 2020 to 30th April 2021. Methods: This analysis included a total of 120 cases. After the informed consent the patients had received comprehensive demographics. Three equal classes of patients were divided into groups A, B and C. Group I had 40 patients and received 2.5 ml isobaric levobupivacane, group II with 40 patients and received 2.5 ml isobaric levobupivacaine and 5μg dexmedetomidine, and group III received 2.5 ml isobaric levobupivacaine and 25 μg fentanyl intrathecally. The outcomes of these groups were analysed in which sensory and motor blockage period were measured from the time the intrathecal drugs were administered. The full SPSS 26.0 version was used to analyze the results. Results: The mean age of the patients in group I was 27.44 ± 7.64 years with BMI 23.19±8.44, mean age in group II was 27.22 ±7.42 years with BMI 24.44 ± 6.16 and in group III mean age was 26.99 ±9.61 years with BMI 24.72 ±4.34. Duration of sensory and motor blockade was observed and resulted that it was earlier in group III as compared to group I and II. Prolonged duration of sensory and motor blockade was observed in group II as compared to groups I and III with significantly P value< 0.001. Conclusion: We concluded that for an adjuvant of 0.5 percent isobaric levobupivalacaine, Intrathecal dexmedetomidine induces both prolonged motor blockage and post operative analgesia than fentanyl. Key words: Levobupivacaine; Spinal anesthesia, Fentanyl, Intrathecal analgesia, Cesarean section; Dexmedetomidine.

In this study, genotoxic effects of repeated sevoflurane anaesthesia were investigated in rabbits with or without antioxidant supplementation. Twenty-one New Zealand male rabbits were included in the study and randomized into three groups as: placebo treated (Group I), vitamin E supplemented (Group II) and selenium supplemented (Group III). Vitamin E and selenium were given intraperitoneally for 15 days before anaesthesia treatment. Anaesthesia was administered using 3% sevoflurane in 4 L/min oxygen for a 3-hour period and continued for 3 days. Blood samples were collected before anaesthesia (Sample 1), after the first, second and third days of sevoflurane administration (Sample 2, Sample 3 and Sample 4 respectively) and the last samples were taken 5 days after the last sevoflurane administration (Sample 5). Genotoxic damage was examined using the comet assay. The degree of damage is assessed by grading the cells into three categories of no migration (NM), low migration (LM) and high migration (HM) depending on the fraction of DNA pulled out into the tail under the influence of the electric field. The number of comets in each sample was calculated (1 × number of comets in category NM + 2 × number of comets in category LM + 3 ×number of comets in category HM) and expressed as the total comet score (TCS), which summarizes the damage frequencies. In Group I, a significant increase in the mean TCSs was observed for Samples 3 and 4 as compared with Sample 1. However, there were no significant differences between Samples 1, 2 and 5. The mean TCS of Sample 4 was significantly higher than Sample 1, 2 and 3 in Group II. Group III demonstrated no significant mean TCSs for any experimental conditions. Statistical differences were also observed between the groups with significant P values. This experimental study points out the presence of DNA damage with repeated sevoflurane anaesthesia and the genoprotective role of antioxidant supplementation on DNA damage in mononuclear leukocytes of rabbits by highly sensitive comet assay.

Objective: the clinical value of spinal quantitative CT (sQCT) and the structural patterns of the vertebral bone were studied Material and Methods: sQCT was performed on 246 patients with a mean age of 57 years for whom conventional lateral radiographies of the thoracic and lumbar spine were available. All patients were suffering from back pain of unknown etiology. the bone mineral density (BMD) of the midvertebral section of 3 lumbar vertebral bodies was determined by means of single-energy-(SE)-weighted QCT (85 kV). Spongiosa architecture and density profile analyses were made in the axial images. This was contrasted to BMD values ascertained in SE QCT. the mean BMD was compared to the number of fractures and the patients were divided into three groups: group I — no fracture; group II — one fracture; and group III 1 fracture Results: the mean BMD was: 134.3 (74.1–187.5) mg hydroxyapatite (HA)/ml in group I; 79.6 (58.6–114.3) mg HA/ml in group II; and 52.4 (13.1–79.1)mg HA/ml in group III. A significant deterioration in spongiosa structure was found with increasing demineralization: strongly rarefied patterns predominated in the fracture groups II and III Conclusion: sQCT provides a good risk assessment of the occurrence of vertebral body insufficiency fractures

The monthly wool growth of three groups of rams was studied at Beltsville, Maryland. Group I received natural daylight (at 38° 53' N.) and was shorn monthly. Group II had a 7:17 hours of daylight to hours of darkness rhythm and was shorn every 6 months, once in winter and once in summer. Group III received natural daylight and was likewise shorn every 6 months. The rams of all groups produced more wool in summer than in winter. This difference was significant (P<0.001). The mean body weight and food intake were both greater in the winter months, which indicated that the seasonal rhythm of wool growth was not a consequence of poorer feeding in winter. The rams which were shorn monthly (group I) grew considerably more wool than the other two groups, but the difference was not statistically significant. The short-day treatment of group II did not increase the annual wool production nor decrease the seasonal rhythm of wool growth. The balance of evidence from this and other experiments indicates that temperature rather than light controls the seasonal rhythm of wool growth.

Background: Studies estimating the Tobacco- specific nitrosamines, (TSNA’s) which are the strongest carcinogens in the saliva oftobacco users and tobacco quitters, are limited.Objectives: To assess and compare the levels of N- nitrosamines (NNN, NNK) in the saliva of tobacco chewers and non -chewers including those who have quit the habit of tobacco use.Methods: The study included 120 patients who were divided into three groups of 40 each: Group I- Smokeless tobacco chewersGroup II- Tobacco chewers who have completely stopped the habit at least 2 weeks prior to sample collection andGroup III- non-chewers. The salivary levels of two tobacco specific nitrosamines; NNN & NNK levels were estimated in the three study groups. Statistical analysis was done by Kruskal– Wallis, one-way analysis of variance (ANOVA) test, Mann-Whitney U test. (p-value < 0.05 was considered to be statistically significant)Results: In Group I, the mean level of NNN was 651.84 ± 359.78 and mean level of NNK was 168.32 ± 131.83. In Group II, the mean level of NNN was 119.52 ± 95.05 and mean level of NNK was 42.78 ± 43.19. In Group III, the mean level of NNN was 3.44 ±6.55 and mean level of NNK was 1.98 ± 3.68. There was a statistical difference in the 3 groups with respect to mean levels of NNN and NNK.Conclusion: The study indicated that salivary tobacco-specific nitrosamines are elevated in tobacco chewers. Saliva can be used to detect TSNA’s and screen for TSNA’s during each patient’s de-addiction process.

Abstract Background. Approximately 5% of COVID-19 patients suffer near fatal disease. Clinical and radiologic features may predict severe disease albeit with limited specificity and radiation hazard. Laboratory biomarkers are eyed as simple, specific and point of care triage tools to optimize management decisions.This study aimed to study the role of inflammatory markers in prognosticating COVID-19 patients.Methodology. A hospital based retrospective study was conducted on COVID-19 adult inpatients classified into three groups as mild disease-recovered [Group I], severe disease-recovered [Group II] and dead [Group III]. Categorical outcomes were compared using Chi square test. Univariate binary logistic regression analysis was performed to test the association between the explanatory and outcome variables. Unadjusted OR along with 95% CI was calculated. The utility of lab parameters (Ferritin, LDH, D dimer, N/L ratio and PLT/L ratio) in predicting severity of COVID-19 was assessed by Receiver Operative Curve (ROC) analysis. P value < 0.05 was considered statistically significant.Results. The mean age was 49.32 +/- 17.1 years. Among study population, 378 were Group I, 66 Group II, and 56 Group III. Median levels of Ferritin among the 3 groups were 62ng/mL, 388.50 ng/mL and 1199.50 ng/mL. Median value of LDH were 95U/L, 720 and 982.50(p <0.001). D-dimer values of 3 groups were 23.20ng/mL, 104.30 ng/mL and 197.10 ng/mL (p <0.001). CRP done qualitatively was positive in 2 (0.53%), 30 (45.45%) and 53 (94.64%) of patients. The odds of patients suffering severe COVID-19 rose with rising values of ferritin, LDH and D-dimer [unadjusted OR 1.007, 1.004 &1.020]Conclusion. One time measurement of serum ferritin, LDH, D-dimer and CRP is promising to predict outcomes for COVID 19 inpatients. Single qualitative CRP was equally good but more cost effective than quantitative CRP. The most specific combination was NLR, Lymphocyte percentage and D-dimer levels done between 7th – 10th day of symptoms.

Abstract: The aim of this study was to evaluate the lung maturity of premature and full-term lambs by analyzing amniotic fluid using the following methods: Clements test, Nile blue cytology test, hematoxylin-Shorr stain, lamellar body count, and radiographic tests. The use of these methods is intended to identify high-risk newborns and provide immediate clinical intervention after birth. Altogether, 56 animals (24 ewes and 32 lambs) were included in the study and divided into 3 groups. Group I consisted of 8 ewes that were at approximately 145 days of gestation; this group delivered 10 lambs naturally. Group II consisted of 8 ewes that were at 138 days’ gestation; this group delivered 11 lambs by cesarean section. Group III consisted of 8 ewes at 138 days’ gestation; this group was administered intramuscular dexamethasone (16mg/animal) 36 hours prior to a cesarean section. Group III delivered11 lambs. Cytological tests were performed using a microscope with a maximum magnification of 1000x, while the Clements test was visually observed by one of the researchers. Amnioticfluid lamellar body counts were measured using transmission electron microscopy. Among the staining methods, hematoxylin-Shorr was reliable, and Group III had a greater number of orangeophilic cells when compared to Group II, probably due to corticoid administration. The Clements test showed pulmonary maturity in approximately 20% of Group I lambs and Group II showed 9.1% of bubbles; however, Group III had the highest pulmonary maturity percentage (36.4%). The lamellar bodies were measured, and all groups had sizes between 0.019 and 0.590μm. Radiographic evaluation revealed that the majority of lambs presented some level of pulmonary radiodensity, indicating an acinar pattern at birth. These results are in line with the expectations of each group. We found that the normal group showed greater pulmonary maturity, whereas Group II presented pulmonary immaturity, which is expected because this group comprised lambs born prematurely and Group III showed pulmonary maturity almost comparable to the normal delivery group (Group I). This is due to the fact that although these animals are premature, the use of dexamethasone helped in pulmonary maturation. Therefore, these pulmonary maturity tests are considered effective when more than one technique is used and can be used routinely in the care of a pregnant ewe in labor, where a simple collection of amniotic fluid can predict a high-risk pregnancy and alert the veterinarian if the newborn needs intensive supportive treatment.

Interest in medicinal plants for the management of myriad of conditions including reproductive disorders refractory to orthodox medicinal care is on the increase. Ficus syncomorus and Datura metel are two of such plants with folkloric evidence of aiding fertility in human. This study investigated the effect of aqueous stem-bark extracts (200 mg/kg) of F. syncomorus and D. metel respectively on the sperm characteristics of Yankasa rams. Twelve (12) matured (15 – 16 months) old rams were used in this study and randomly assigned into three (I, II, III) groups of four (4) animals each. Group I served as the control while II and III served as the treatment groups and received daily oral doses (200 mg/kg) of F. syncomorus and D. metel extracts respectively for 7 consecutive days. Semen was collected from all the groups at the end of the treatments using Electro-ejaculation method and evaluated by light microscopy. The mean semen volume (68.70+4.2 to 65.62+2.00) and percentage progressive motile cells significantly (p<0.05) reduced 7 days post treatment in group III (84.05+1.3) compared to the control (85.20+1.32) and the group II (86.56+0.40) animals. The mean sperm count, the percentage liveability and the haematological parameters and erythrocytic indices (10.81±0.24 for group 111 to 12.54±0.30 for group1) significantly (p<0.05) decreased in group III compared to the values in the control and group II rams. Abnormal sperm morphology (bent mid-piece, curved tail, headless tail, tailless head) significantly (p<0.05) increased in D. metel group (7.26+0.12) compared to F. syncomorus (5.02+0.04) and control groups (5.62+0.01) respectively. D. metel aquesous extract adversely affected sperm characteristics with significant effect on semen volume, sperm morphology and counts as well as haematological parameters. Exposure of animals to D. metel at the dose used may impair sperm fertilizing ability, thus leading to reduced ram fertility. While F. syncomorus extract appears a potential drug candidate for improving fertility.

Background: The present study was conducted to assess the outcome of intrathecal analgesia in multiparous women undergoing vaginal delivery. Subjects and Methods: The present study was conducted among 80 multiparous women ages ranged 18- 40 years. All patients received 0.5 ml of intrathecal injection of 2.5 mg bupivacaine 0.5% and 1 ml dexamethasone 4 mg plus a 0.5 ml adjuvant. The adjuvants in group I patients were 100 μg morphine, 25 μg fentanyl in group II, 5 μg dexmedetomidine in group III and normal saline in group IV (control group). The primary and secondary outcome was the duration of pain relief, the analgesia onset time, the maximum level of sensory block, the visual analogue scale (VAS) was recorded. Results: The mean duration of analgesia in group I was 182.4 minutes, in group II was 170.5 minutes, in group III was 200.4 minutes and in group, IV was 140.2 minutes. The onset of analgesia was 3.9 minutes, 2.8 minutes, 2.7 minutes and 4.5 minutes in group I, II, III and IV respectively. S1 sensory regression time (minutes) was 181.4, 157.4, 185.3 and 130.6 in group I, II, III and IV respectively. Modified Bromage scale 5 minutes, 15 minutes and 30 minutes after IT in all groups was 0.0. VAS was 1.3, 1.6, 1.6 and 3.1 with significant differences in all groups (P< 0.05). There was non- significant difference in mean age, weight, height and gestational age between all groups (P> 0.05). There was a non- significant difference in APGAR 1, 5, umbilical pH immediately after delivery, neonatal HR after 5minute, 15 minutes and 30 minutes in all groups (P> 0.05). Conclusion: The authors found that dexmedetomidine is a safe and effective adjuvant to intrathecal bupivacaine-dexamethasone in multiparous women undergoing normal vaginal delivery.

Aim: This preliminary study aimed to estimate and correlate the relationship between salivary flow rate and levels of salivary triglycerides, cholesterol and total lipids in children with and without early childhood caries. Study design: Ninety children aged 3 – 6 years were divided into three groups of 30 each based on their decayed missing filled tooth (dmft) score, group I (dmft score = 0), group II (dmft score ≥4 and ≤ 9) and group III (dmft scores ≥ 10). Whole unstimulated saliva was collected in a sterile graduated cup over a period of 5 minutes and was quantitatively analyzed for levels of salivary triglycerides, cholesterol and total lipids. Data obtained was subjected to statistical analysis by one way ANOVA, Post-Hoc tukey and Pearson’s correlation test. Results: Salivary flow rate was 1.20±0.36, 1.01±0.37 and 0.86±0.31 ml/min in group I, II and III respectively. The mean levels of salivary triglycerides in group I, II and III was 3.57±0.43mg/ml, 6.11±1.70mg/ml and 6.03±1.73 mg/ml, respectively. The mean levels of salivary total lipids were higher in group II and III, ie 22.51±2.87 mg/ml and 22.68±2.54 mg/ml respectively. The mean level of salivary cholesterol was highest in group III (8.03±2.91 mg/ml). Salivary triglycerides and total lipids showed a significant positive correlation with dmft scores of children (p≤ 0.001). Salivary cholesterol also had a positive association with dental caries experience of children but was not significant. There was a negative correlation between salivary flow rate and levels of salivary triglycerides, cholesterol and total lipids. Conclusion: Children with ECC (group II and III) had lower salivary flow rate and higher levels of salivary triglycerides and total lipids compared to caries free children (group I). Levels of salivary cholesterol did not differ between caries free and children with ECC.

This work assess serum levels of soluble Fas form (sFas) in patients with different stages of laryngeal squamous cell carcinoma(LSCC) to investigate its prognostic significance. We correlate its levels with the morphological changes of peripheral blood cells via buffy coat examinatin. The study population included 70 patients clinically diagnosed and pathohistologically confirmed LSCC in addition to 20 healthy controls. According to TNM classification 33(47.1%) patients were in stage I (group I) and 24(34.3%) in stage II (group II), 13(18.5%) in stage III (group III). The results revealed that the mean serum level of sFas (pg/ml) in the control group was 51.2, in group I was 66.33, in group II was 81.33 and in group III was 112.45. Statistical analysis of the mean of sFas by ELISA test in the patients' groups in comparison to the control revealed a significant increase of both group II and III in comparison to the control group (P < 0.01) but there was no significant difference (P > 0.05) between group I in comparison to either the control or group II. There was a significant difference (P < 0.05) between group I in comparison to group III. LM examination revealed massive extent of the apoptotic cells in group III when compared to both group I and group II. EM examination of the buffy coat revealed apoptotic changes, mainly in the peripheral blood mononuclear cells (PBMNCs), represented by surface membrane ruffles and blebs with clumped nuclear chromatin and vacuolated cytoplasm. In conclusion, this study may help us to better understand one of the escape mechanisms in cancer larynx. This mechanism is represented by the significant increase in both the serum level of sFas and the morphological apoptotic changes that detected in PBMNCs. Soluble Fas may contribute to the progression of laryngeal cancer. It can be used as an attractive target for anticancer therapy and may be considered as a marker of disease progression and poor prognosis in laryngeal cancer.
