| Summary, etc. | Objective: To  see  the  effects  of Raj Nirwan  Bati  (RNB)on  the  hematobiochemical  parameters,  coagulation  tests,  and  histopathological  changes  in the lungs, liver, kidneys and spleen and also to evaluate the immunomodulatory activity of RNB in Wistar rats.Methods: A  total  of  24  adult  albino  Wistar  rats  (of  bodyweight  200-250  g)  of  either  sex  were  divided  into  3  groups.  In  the  normal  control  group (n=8),  no  drug  was  administered  and  in  the  rest  of  the  groups  (A  and  B), RNB@  26  mg/kg  body  weight./day  and  260  mg/kg  body  weight/day respectively  were  administered  orally  for  a  period  of  14  d.  The  blood  samples  were  collected  from  the  jugular  vein  at  zero  d  (before  drug administration)  and  after  the  14thd  of  drug  administration  in  both  groups  (A  and  B).  The  organ  samples  (lungs,  liver,  kidneys,  and  spleen)  were collected after euthanizing the  rats using Ketamine anesthesia overdose intraperitoneally (IP) after  the 14thd of drug administration. White  Blood Cells  (WBC), Red Blood  Cells  (RBC), Hemoglobin  (Hb), Hematocrit (HCT), Mean Corpuscular Volume (MCV), Mean Corpuscular Hemoglobin(MCH),  Mean  Corpuscular  Hemoglobin  Concentration(MCHC),  number  of  platelets,  Differential  Leucocyte  Count(DLC)  i.e.  the  percentage  of  neutrophils,  lymphocytes, eosinophils, monocytes and basophils, neutrophil adhesion percentage, Prothrombin test (PT), Activated Partial Thromboplastin Time (APTT), fibrinogen, D-dimer, Lactate Dehydrogenase (LDH), urea, creatinine, Aspartate Amino Transferase (AST), Alanine amino Transferase (ALT),  Alkaline Phosphatase (ALP), C-Reactive Protein (CRP) were evaluated and histological examination of organs were done.Results: After statistical analysis, it was found  that the decrease in TLC, RBC, Hb, HCT, and LDH in Wistar rats after RNBintervention in Group A as compared  to  that  of  before RNB intervention,  was  found  to  be  statistically  significant  (P=0.001,  P=0.002,  P=0.001,  P=0.039,  and  P=0.008).  On  the other hand, an increase was observed in MCV, Urea, Creatinine and ALT values in the Wistar rats after RNB intervention in Group ‘A’ as compared to that  of  before RNBintervention  and  this  increase  in  values  was  statistically  significant  (P=0.007,  P=0.001,  P<0.001  and  P=0.038).  After RNB intervention  in  Group  B,  the  increase  in  MCH,  fibrinogen  concentration,  and  monocytes  percentage,  was  found  to  be  statistically  significant (P=0.004,  P=0.033,  and  P=0.001)  as  well  as  the  decrease  in  PT  and  APTT  was  statistically  significant  (P=0.007and  P=0.002). After  comparing  the Mean  Hematobiochemical  and  coagulation  test  parameters  in  the  rats  of  Group  A  and  Group  B,  after RNBintervention,  it  was  observed  that  the concentration  of  Urea,  Creatinine,APTT,  and  D-dimer  were  less  in  Group  B  as  compared  to  that  of  Group  A  and  this  difference  was  statistically significant(P<0.001,  P<0.001,  P<0.001  and  P=0.022).  Histologically  the  findings  in  the  lungs  of  group  B  were  more  distortion of  lung  architecture,  most of the alveoli become collapse and make emphysematous changes, more diffuse inflammatory infiltrate within interalveolar septa and around bronchioles as compared to Group A. In the liver of group B rats, the histological findings were mild  to moderate distortion of lobular architecture,  healthy  hepatocytes  with  more  activation  of  kupffer  cells  as  well  as  larger  and  more  aggregates  of  inflammatory  cells  as  compared  to  group  A.  Histological findings of kidneys in group A and group B rats were similar to that of control group rats.Conclusion: The  results  suggest  that  the RNBis  having  an  immunomodulatory  effect.  It  might  be  helpful  in  the  restoration  of  coagulation  factors and can help treat  the COVID patients. No harmful effects on the lungs, liver, kidney, and spleen were seen. These findings may act as baseline data for planning further clinical trials in human study subjects to evaluate the effects on various comorbidities. |
