Background: Diabetes in rats is a condition used in research,It is typically induced using a chemical toxic to pancreatic cells, such as alloxan, Coriander seeds and leaves are both cooling in nature.They are particularly effective in reducing body heat and aiding digestion.

Methods: Twenty male albino rats were divided into four groups, with five rats each: Group 1 - control; Group 2 - coriander seed extract; Group 3 - diabetic; and Group 4 - diabetic + coriander seed extract.

Result: Our current results showed that diabetic rats in the third group had an increase in Liver Enzymes and Kidney Function levels on the first day after induction of infection when compared to the first group. When treating rats in the fourth group with Coriander Seed Extract we noticed a decrease in Liver Enzymes and Kidney Function on the last day when compared to the third group. We conclude from our current study that with Coriander Seed Extract improves Liver Enzymes and Kidney Function in male rats.

Diabetes in rats is a condition used in research. It is typically induced using a chemical toxic to pancreatic cells, such as alloxan, leading to symptoms similar to those of human diabetes, such as high blood glucose, increased thirst, frequent urination and weight loss. These studies aim to understand the mechanisms of the disease and test potential treatments. It has been observed that some plant extracts and treatments may improve glycemic and lipid profiles in affected rats (Fajarwati et al., 2023; Hamadjida et al., 2023).
       
Diabetes in both humans and rats tend to feature similar signs/symptoms, including; high blood glucose, thirst (polydipsia), urination (polyuria), glucose being lost through urine (glucosuria), hunger (polyphagia), stomach problems and fatigue-along with unexplained weight loss. e.g. (Edo et al., 2024).
       
The causes of diabetes vary depending on the type, but generally include insulin resistance or insufficient pancreatic production. Causative factors include genetics, overweight and obesity, physical inactivity, unhealthy diets, aging and psychological stress. The majority of people who have type 2 diabetes develop it from a combination of their genetic predisposition and lifestyle habits (Al-Masri and Khorashad, 2023; Onyibe et al., 2021), whereas type 1 diabetics have diabetes due to an autoimmune disease where the immune system destroys the beta cells of the pancreas (Al-Masri et al., 2024; Onyibe et al., 2021).
       
Coriander seeds and leaves are both cooling in nature.They are particularly effective in reducing body heat and aiding digestion. Coriander water: Soak a teaspoon of coriander seeds in water overnight. Strain and drink the water in the morning (Ballı et al., 2024).
       
One benefit of coriander is that it reduces skin inflammation. both cineole and linoleic acid are found in coriander, which also has diuretic qualities, lowers blood pressure, is a rich source of calcium, controls diabetes, and heals wounds and mouth ulcers.promotes digestion and treats osteoporosis  (Elbatawy et al., 2025).
       
In addition to being an ingredient in Indian food, coriander is also good for helping maintain the health of the liver since it has been used for centuries in traditional Ayurvedic medicine for the treatment of liver disorders and improving digestion (Boujbiha et al., 2025; Gurram et al., 2022).
Induction of alloxan in male rats
 
After 24 hours of fasting, 10 male rats received an intraperitoneal injection of alloxan at a dose of 150 mg/kg BW. This chemical can cause hypoglycemia due to insulin leakage into the pancreas and beta cell damage according to Kim, 2024. The successful completion of the induction process was confirmed the next day after measuring the glucose levels of the 10 rats using a blood glucose meter (PreciChek Autocode, AC-302, Germany).
 
Animals
 
Twenty adult male albino rats (200-225 g) were used in an experimental and were obtained from the Biotechnology Research Center, Al-Nahrain University. The rats were kept at 50% (±10%) relative humidity, temperature 20-25°C and 12 hours darkness, then the animals were divided into 4 groups of 5 animals each. Water and food were provided ad libitum throughout the experiment. The rats were separated into special cages and divided into four cages.
 
Experimental design
 
Twenty male rats were divided into four groups, each containing five rats.
Gp 1:. A healthy, non-diabetic group that received only saline.
Gp 2:. A group of non-diabetic animals that received Coriander Seed Extract @ 250 mg/kg according to (Dewi et al., 2025).
Gp 3:. A group of diabetic animals that did not receive treatment dose (150 mg/kg body weight) according to (Kim, 2024).
Gp 4:. A group of rats with diabetes that received Coriander Seed Extract.
       
A 4-week experimental period followed by euthanasia and dissection of animals, collection of samples (tissue and blood), centrifugation of blood for evaluation of biochemical indices and histological fixation of lung and kidney tissues in formalin-containing glass containers were performed.
 
Biochemical assays
 
The colorimetric assay kits for liver and kidney function and lipid profiles were acquired from Spectrum-diagnostics in Cairo, Egypt According to (Alyasiri et al., 2025; Alankooshi et al., 2023; Abd El-Rahmana et al., 2024).
  
Ethical approval
 
The experiment that will be performed included ethical approval obtained through the Biotechnology Research Center - University of Nahrain for November 2024.
 
Statistical analysis
 
The statistical software package called Statistical Package for Social Sciences (SPSS) (R) (Version 26 for Windows) was used to conduct one-way analysis of variance (ANOVA) on the data collected.
Effect of coriander seed extract on body weight levels
 
Through Fig 1 the statistical analysis shows the effect of sugar levels on the first and last day of the experiment, The weight of the animals that were infected with diabetes decreased on the last day when compared to the first day, while for the animals that were infected with diabetes and treated with Coriander Seed Extract, we notice an increase in weight compared to the weight on the first day.

The effect of coriander seed extract on liver function
 
As illustrated in Fig 2, there was statistically significant elevation in ALT and AST levels within the diabetic (Gp3) laboratory animals compared to the normal control. Conversely,  ALT and AST activity in the diabetic(s) treated with the coriander seed extract (Gp4) decreased as compared to Gp3.

The effect of coriander seed extract on kidney function tests
 
The study results recorded on a Fig 3 demonstrate an overall improvement in kidney function among all tested groups. The diabetic group (Gp3) of animals exhibited a significant elevation in urea and creatinine levels compared to animals from both the control groups (Gp1 and Gp2). Additionally, when comparing the diabetic animals (Gp3) to the animals treated with coriander seed extract (Gp5), there was a significant drop in both urea and creatinine levels for the animals receiving coriander seed extract.

Diabetes is a major health issue, with an estimated 366 million people globally predicted to have the disease by 2030, up from 171 million in 2000 (Wild et al., 2004; Guzman-Vilca et al., 2025; Al-Saeedi et al., 2026: Al-Obaidi et al., 2022).
       
Important organs for regulating blood glucose levels include the kidney and liver. Diabetes results in significant changes to the liver and pancreas, which compromise glucose metabolism and homeostasis (Lema-Pérez et al., 2021; Gerich et al., 2010).
       
Diabetes induced chronic and permanent hyperglycemia leading to excessive oxidative stress compromising the antioxidant defense mechanism and increasing the production of additional free radicals in preclinical models (González et al., 2023; Al-Obaidi et al., 2022; Al-Dulimi et al., 2025).
       
Because of oxidative stress, alloxan has strong toxic effects on islet β cells, which leads to pancreatic β cell failure. Alloxan caused hyperglycemia in this study along with significant pathological alterations in the islets of Langerhans, such as necrosis, degeneration and hypocellularity (Robertson et al., 2006).
       
Our study agrees with those who conducted numerous experiments on the role of medicinal plants in treating or preventing diabetes in laboratory animals. Among their recommendations was that further experiments be conducted on the role of plants in influencing diabetes (Ighodaro et al., 2017).
       
Alloxan-injected rats have been shown to lose weight after thirty (30) days of being diabetic (Fig 1). The weight loss observed in these rats is consistent with the results obtained from studies by Maithili et al., (2011) and Solikhah et al., (2021), as diabetes is known to cause weight loss in rats. The values of ALT and AST activities and urea and creatinine concentrations (Fig 2 and 3) all significantly increased in the diabetic (alloxan-treated) groups of rats, confirming the greater risk for rats with diabetes to have abnormalities in liver and kidney function tests, as shown in El Batran et al. (2006) and Adesokan et al. (2009).
       
When treating diabetic laboratory animals in the fourth group with coriander seed extract, we noted in (Fig 1) a clear improvement in the weight levels of laboratory animals on the final day when compared to the third group. In addition, the results reported here support the findings of both El-Hennamy et al. (2025) and Elbatawy et al. (2025).
       
We noted in (Fig 2 and 3), the fourth group that was treated with coriander seed extract, a high significantly p≤0.05 improvement in liver and kidney functions in laboratory animals when compared to the third group. The findings of this presented data correspond with the results obtained from two studies by Hassan et al. (2022) and Nisa et al. (2025) documenting the nutritional effectiveness associated with coriander seeds and suggest the need for continued experimental evaluation of this plant.
We conclude from our study that coriander seed extract improves biochemical indicators in the liver and kidneys of diabetic rats and we suggest further research on coriander seed extract in the future.

We noted in (Fig 2 and 3), the fourth group that was treated with coriander seed extract, a high significantly p≤0.05 improvement in liver and kidney functions in laboratory animals when compared to the third group. The findings of this presented data correspond with the results obtained from two studies by Hassan et al. (2022) and Nisa et al. (2025) documenting the nutritional effectiveness associated with coriander seeds and suggest the need for continued experimental evaluation of this plant.
We conclude from our study that coriander seed extract improves biochemical indicators in the liver and kidneys of diabetic rats and we suggest further research on coriander seed extract in the future.
