FORMULATION AND EVALUATION OF CHRONOMODULATED PULSATILE THERAPEUTIC SYSTEM FOR EARLY MORNING SURGE IN BLOOD PRESSURE

Objective: The objective of this study was to design and developed a rupturable coating type of pulsatile press coated tablet, which releases drug early in the morning hours. This delivery system was helpful to control an early morning surge in Blood Pressure because cardiovascular events occur more frequently in the morning. This delivery system would be useful for the prevention of cardiovascular events in hypertensive patients.Methods: Initially core tablet was prepared by using Captopril HCl as a model drug, which is having Angiotensin-converting enzyme inhibition activity and different concentration of cross carmellose sodium as a superdisintegrant by the direct compression method. Core tablet was press coated by using HPMC K4M and Ethyl Cellulose in different ratios as a press coating polymers.Results: Core tablet was evaluated for different evaluation parameters and the formulation which shows least disintegration time has been selected for further study. Dissolution profiles clearly indicate that Captopril released from the press-coated tablet depends on the amount of an HPMC/EC ratio used.Conclusion: From in-vitro dissolution study it was concluded that the lag time decreases with increase in concentration of HPMC K4M. When the concentration of hydrophilic polymer was increased, i.e. HPMC K4M, hydration property of the system increases, causing more rapid dissolution or rupturing of the external shell resulting in the reduction in lag time.Â

Intrahepatic cholestasis of pregnancy- case series done in a tertiary care hospital

Intrahepatic cholestasis of pregnancy (ICP) also known as obstetric cholestasis is a liver disorder of pregnancy which is characterised by maternal pruritus usually in the third trimester, raised serum bile acids and increased incidence of adverse fetal outcomes and usually complete resolution of symptoms post-delivery. The etiology of ICP is complex and multifactorial as is the mechanism by which fetal complications occur which is yet not completely understood. The introduction of ursodeoxycholic acid in the management of ICP has provided significant improvement in maternal symptoms as well as fetal outcome. We present a case series of 5 cases of obstetric cholestasis which presented in our tertiary care hospital which could possibly help and guide obstetricians in the future who are dealing with dilemma in diagnosis and management of this condition.  

Pluronic F-127 hydrogel for stem cell research: a bibliometric analysis using Scopus database

Stem cell research holds immense promise in regenerative medicine. However, the successful utilization of stem cells relies on their inherent properties and the appropriate support matrix that provides an optimal environment for growth and differentiation. Optimizing their delivery and retention at the target site is crucial to enhance stem cell-based therapies' effectiveness. In recent years, hydrogels have emerged as a popular choice for culturing and delivering stem cells due to their unique properties, including biocompatibility, tunable physical and chemical characteristics, and mimicking the native extracellular matrix. Among the various hydrogels available, Pluronic F-127 (PF-127) has gained significant attention in stem cell research. This paper aims to study the publication trends of research that discuss the utilization of PF-127 hydrogel for stem cell research. The analysis is based on data extracted from the Scopus database using bibliometric methods. The results revealed the publication trends, collaboration patterns among authors and institutions, research areas, influential journals, funding agencies, and thematic connections in this field. By understanding the current state of research and identifying key areas of focus, this analysis provides valuable insights for researchers and practitioners interested in harnessing the potential of PF-127 hydrogel in regenerative medicine and tissue engineering

Evaluation of Xylazine, Acepromazine and Medetomidine with Ketamine for General Anaesthesia in Rabbits

A randomized, prospective, blinded experimental study was conducted in 32 rabbits of either sex to compare  the anaesthetic and physiological effects of ketamine with different pre-anaesthetics. Rabbits were  randomly divided into 4 equal groups. Xylazine 6 mg/kg in animals of group xylazine-ketamine (XK), acepromazine  2 mg/kg in animals of group acepromazine-ketamine (AK), medetomidine 125 μg/kg in group  medetomidine-ketamine 1 (MK1) or medetomidine 250 μg/kg in group medetomidine-ketamine 2 (MK2)  were administered by intramuscular injection (IM). Five minutes later, ketamine 60 mg/kg was administered  intramuscularly to all the groups. The rabbits were observed for the onset of weak time, down time,  the time to loss of righting reflex, pedal reflexes and response to surgical stimuli. Heart rate, respiratory  rate and rectal temperature and arterial oxygen saturation of haemoglobin (SpO2) were recorded up to 60  min. Weak time, down time and time to loss of righting reflex were the shortest in animals of group MK2  as compared to the other groups. Pedal reflexes remained intact in all the animals of XK group, but were  abolished in 50% of the AK group, 75% of the MK1 group and 100% of animals in the MK2 group. Pain  was evinced during surgery by all the animals in group XK, 5 animals in group AK and 4 animals in group  MK1. The best analgesia was achieved in the animals of group MK2, where none of the animals showed  pain on surgical stimulation. Heart rate and SpO2 decreased significantly (P<0.01) in the animals of groups  XK, MK1 and MK2 but respiratory rate and rectal temperature decreased significantly (P<0.01) in all the  groups. However, all the animals recovered from anaesthesia without complications. It was concluded that  medetomidine 250 µg/kg and ketamine 60 mg/kg produced excellent anaesthesia to allow pain free surgery  and may be considered suitable for anaesthesia in New Zealand White rabbits.

Comparative Evaluation of Masson's Trichrome and Picrosirius Red Staining for Digital Collagen Quantification Using ImageJ in Rabbit Wound Healing Research

The therapeutic potential of Pluronic F127 (PF127) hydrogel loaded with adipose-derived stromal vascular fraction (AdSVF), mesenchymal stem cells (AdMSC), and conditioned media (AdMSC-CM) for repairing full-thickness skin wounds was evaluated using a rabbit model. The rabbits were randomly divided into eight groups with six animals each and treatment was given as per the predetermined protocol (3 doses at one-week interval): Group A (Control), Group B (AdSVF), Group C (AdMSC), Group D (AdMSC-CM), Group E (PF127), Group F (AdSVF + PF127), Group G (AdMSC + PF127), and Group H (AdMSC-CM + PF127). Skin tissue samples were collected from the healing wounds on day 28 for staining and collagen quantification. Collagen density (Area %) was quantified using tissue sections stained with Masson's Trichrome (MT) and Picrosirius Red (PSR) stain using the Colour Deconvolution plugin of ImageJ and RGB stack method, respectively. These techniques function based on separating different colour channels in the stained tissue sections to isolate the collagen fibers and then quantifying them through thresholding and image analysis. Across the treatment groups, both staining methods generally showed a trend of increased collagen density compared to the control group. For most groups, PSR staining consistently indicated slightly lower collagen densities than MT staining. However, the overall trends were similar in both staining. The comparison between PSR and MT staining methods revealed that both techniques effectively assess collagen density in healing wounds. However, there were subtle differences in the absolute values obtained, with PSR staining tending to yield slightly lower collagen density measurements than MT. These differences can be attributed to the distinct mechanisms of these staining methods. Therefore, both staining methods can digitally quantify collagen density in wound healing research
